How did you find out your little one had digeorge if you don’t mind me asking? And how is he now?
Hi @Wombleofwimbledon1984 I don't mind at all 
The midwives on the maternity ward picked up that 'something' was wrong shortly after he was born and he got transferred to the neonatal unit. It turned out that he had a heart defect (not picked up antenatally) and one of the doctors mentioned DiGeorge because he was struggling to feed as well and had a small mouth.
We got transferred to a tertiary hospital the day after and DS had his OHS when he was 5.5 weeks old. They did the genetic testing while we were there (which is standard for all babies with heart defects) and brought him home at 8 weeks.
Health-wise he is doing really well now. He is stable from a heart perspective but has struggled with picking up lots of bugs and is currently on prophylactic antibiotics (ie ongoing ABs to boost his immune function). He is on the shielding list which is really tough as we are used to being out and about a lot.
On the development side, he has lots of challenges, especially with speech and language and his fine motor and functional skills. We have speech and language and OT input and he has a 1-1 at his usual pre-school (obviously shut at the moment).
He is 3 so he is sometimes an absolute delight and sometimes really hard work! He is generally very happy and cuddly, always laughing and tearing around the place, climbing and jumping on the bed and throwing water around in the garden. So, pretty standard for a toddler!
