Hi I just wanted to add my input as a mother of a T1 child. He was diagnosed at 13 months old. He is now just over 8 years.
For all parents of newly diagnosed diabetic kids, when their Blood Glosucose is out of whack it is NOTHING you are doing! Okay? In the 7 years of my son being diabetic he has NEVER been stable for more than maybe three days - but the HbA1c readings are of more concern to the Dr's than what you are actually seeing on a daily basis. He has finally been put on a pump to hopefully stabilise his blood glucose because basically we were doing everything possible and as the diabetic nurse put it - the output readings were not doing the work we put in with our son any justice. I was also told by the consultant that the older the child is when they are diagnosed the more likely they can control the Blood Glucose levels with just two injections a day, but with younger children it is much harder. This is his general fndings from all the children he has looked after over the years so it is nothing personal to any one child.
HOWEVER - kids are constantly growing, changing every day - their hormones are all over the place, they can go from having an extremely active day or hour to doing absolutely nothing - they have constant worries and frustrations which can affect their Blood Glucose levels - like not doing well on the nintendo! The things that makes kids blood boil generally will make a diabetic kids blood glucose rise! Only really worry about high blood glucose when there are ketones and I second getiing a ketone meter - it is far more accurate than urine readings.
I want to reassure you about having a child who is a fussy eater and diabetic.
My son was an extremely fussy eater. Something that frustrates the hell out of many parents but when your child is diabetic it's not only frustrating but extremely scary.
The first thing we did was make a decision that even though he was at an age too young at the time to understand how to do this, we would never allow him to use his diabetes as a way to scare us into allowing him to eat whatever he wants. This takes a lot of strength and determination as a parent but we did discuss what we were doing with the dietician and she agreed with how we were approaching it.
I found some GI diet books very good (We've got most of the books by Rick Gallop)! There are plenty of healthy alternative foods like cookies, and muffins, that I found great to bake with my son, and I didn't worry as much if he didn't he everything healthy for his dinner, when I knew he had already enjoyed a healthy snack.
But in terms of getting my son to eat ANYTHING for dinner - I would put the food on my son's plate, if he didn't eat it (we gave a time frame of 25 minutes) the food was taken away. We didn't try to force him or enter into any frustrated dialogue about it. He didn't get an alternative and had to wait until the next planned meal time (that may be snack or actual meal). THEY DO LEARN! THEY DO NOT STARVE!
What you mustn't do is give in and straight away give your child something they would prefer to eat. Even with our younger child the choice is to eat what they have been given, or not - but they won't be eating again until the next planned meal (for how strict and determined we were with our son, my husband struggled with this for our non-diabetic daughter - Daddy's Girl! and would give in to her, until he realised he was pandering to her and making a rod for his own back! Now, he does the same with her as we did with our son, and she too is a better eater for it!)
We did this, it was very stressful and it did get to a point when the HUNGRY MONSTER came when our son was two years old. Our son hadn't been made aware of the hungry monster, until the day he refused to eat his dinner and subsequently he had a severe hypo in the middle of the night. This hypo scared the life out of all of us, he was screaming and convulsing. We treated it straight away and when he came around he told us of the dark monster with the green eyes. That was the hungry monster we found out (one of the first times I've ever experienced quick thinking!

) . From that point on even the other kids in the nursery would tell him to eat his dinner, otherwise the hungry monster would come.
I wouldn't advocate intentionally allowing your child to become hypo - we didn't expect to experience anything like we did - that one and only time (he has had hypos in the past - his lowest being 1.3 and he has still been running around and we've been completely unaware until doing a routine BG check) so I would hope that the tale of the Hungry Monster could serve as warning to other children, rather than having him actually visit them in person(?). NEVER bribe your child to eat to stop them getting poorly, because that will be a rod you make for your own back for years to come.
There was a time when he was hospitalised with gastro-enteristis (sp?) He wouldn't eat, and all the (young, newly qualified) doctors were concerned about was getting him to eat, because he was diabetic - it was important, otherwise they 'threatened' to put him on a Glucose Drip. I repeatedly told them I would prefer them to do that - because my son had eating problems already, I didn't want to try and force him to eat then becase I knew it would cause him more problems later, to a point where he could become phobic of food. They were not happy with my stubborness at all - and even thought they'd be able to encourage him to eat (and failed). When the dietician came to see him I explained the issues the Doctors were having with me and she was on my side. She called his consultant down who said "what normally healthy person who is suffering with G.E. would want to eat anyway? Of course he doesn't want to eat - put him on a Glucose Drip and he will eat when he is ready!".
Have you been told about the books "Pete the Pancreas" and "Novo Crew "- Diabetes Books, which are very simply written for kids to explain about Diabetes and why they need to have Blood Glucose readings and injections. If you haven't they are free to download from the Diabetes UK site (under publications I think!). I also have lent them to many a newly diagnosed adult as well. Sometimes literature designed for adults are still written for the medically knowledgable rather than the lay person and they certainly helped me understand diabetes better.
But none the less he is now a healthy 8 year old who enjoys Swimming, Karate, Cubs and a lunchtime sport activity almost every day when he is at school. Above all, no one would believe that this child who would have us tearing our hair out (I would often be in tears) can now tuck away more food than me! (Mostly healthy food, and because he is active and takes after his Dad - is of the right weight for his height!).
