Hi
@Worriedmum26, I've only had Medtronic pumps so can't offer any opinions on the Omnipod I'm afraid, but I was told by my DSN that they aren't as accurate with smaller doses. She did mention a study had been done but didn't give any details
if your son is on small doses you might want to have a look and see if you can find the study and have a read. I know lots of children do use the Omnipod.
For me, I would go with Medtronic, but it's a personal choice, only you and your son can decide what's right for him
