I have and still find it really full-on. The actual age difference between DS and DD is 21 months. DS is developmentally delayed by about 9 months to 1 year, so it is the equivalent of having a 10 month age gap in this house. It is hard, but as a previous poster answered, you just have to do it. You can stress and get upset or you can just realise that you don't have a choice. I wouldn't have had such a small age gap if DS had his diagnosis earlier, but that is neither here nor there. DD is 10.5 months old now and I still can't leave them together without being in arms reach to get DD if DS gets rough or tries to cuddle her to death. It is exhausting. I have no parents here and my in-laws aren't very involved. Fortunately I have an Aunty who helps me out, but that's about it. So it is really hard, but if I can do it with such a small "adjusted" age-gap and very limited help, then you should be just fine. Think about all of those parents who have twins and triplets My hat goes off to them. Best of luck - you will cope JUST fine
