Hi Jacquie. That is great re getting a pump. My daughter Amy is now 2 1/2 and she has had hers for 5 months now. Our life has changed dramatically since getting the pump and i would never return to injections, especially for a child this age. I would say that the 1st 4 months are really hard work getting the basal correct, especially with illnesses and growth spurts etc and it will take up so much of your time, however i will never look back and my daughter has changed dramatically since getting her pump - less moody, more energy!
I went on to an ebay site to get brilliant pump bags from a lady who makes them in america, about £7 each, well worth it. Amy wears her pumps in her bag which is on a velcro elastic around her waist, even at nightime.
You will have to carb count, but there is so much flexibility with the pump, particularly with daytime snacking, refusal to eat and times of illness.
We still have to test Amy during the night though which is hard, but at the end of the day it is her health that matters. Good luck!
