Hi Jodie, none of us know what is in store for any of us, you shouldn't let your worry about diabetes stop you having children. Many diabeteics have healthy pregnancies and children.
I made a decision not to have a third child when 7 years ago I was diagnosed with Retinitis Pigmentosa-a degenerative sight condition and a 1 in 2 chance my children will inherit it. When a close friend of mine was diagnosed with breast cancer, it put things in perspective and my husband and I decided to go ahead and have the 3rd child we wanted. Unfortunately halfway through that pregnancy my eldest son, 9 at the time, was diagnosed with Ewing's Sarcoma, a bone cancer, in his skull. He went through hell, chemo radiotherapy and lots of sugery. The cancer came back when he was 11,after a year in remission. We were told there was no treatment for him. We couldn't accept that we were going to lose him and we sought a second opinion. we saw many doctors, and he was offered experimental treatment, the doctors only expected it to give him more time. They were wrong! He is 16 now doing GCSEs and last week he was given the all-clear. He's on medication, and has some permanent hair loss, but otherwise he is in good health!
I have been diabetic since I was 19, and if any of my children do happen to inherit it, although no-one else in my family has it, I really do know that there are worse things in life.
I know it's hard not too worry, especially after what happened to your mum, but with good care, I'm sure you and any babies you have in the future will be fine. There are huge advances being made with stem-cells and genetics, and there's always hope for a cure in the future. Live in hope
