Okay, my son will be 5 in December and has DS. When he was born he had a medical emergency that we hadn't seen or been detected in scans etc, he needed NICU and an operation (at 10 days old) so that part was hard and we just focused on getting him home.
Since birth his sisters, then 6 and 9 have adored him. He was not a difficult baby, I worried about him during his first year as he had some personal, medical hurdles to clear. But since then he has enjoyed good health.
We love him absolutely, I worried before he was born but the minute I held him, I knew we would always do our best for him but the surprising thing was how much he has helped us! He has a magical personality ( don't want to be twee, but he just has) he makes friends wherever he goes. He has just settled into mainstream reception after largely being at home and doing some preschool sessions. This was our choice as a family but I personally know lots of families with children with DS who work. Off the top of my head, I know two with childminders, two at nursery and one with a nanny share situation. Working is absolutely possible but because of medical needs, most children with DS end up with a lot of hospital clinic appointments during year one. After that it often lessens considerably.
I'm trying to be practical so I'll sum up his baby and toddler hood, his development has been slow/normal, dreadful phrase but so far he has followed typical patterns of development but v v slowly. So he sat later, crawled later and didn't walk until 2.5. Now reading this it might seem a bit depressing but (although at times I have minded v much for him) he has been a huge joy for us. His father dotes on him, they have a fabulous thing going, even though I hardly handed him over to anyone for about the first 6 months!!
His sisters wouldn't be without him, they have said so themselves. Because he is one of three children, sometimes he had to take a turn as a baby and he didn't mind one bit. He actually proved to be more flexible, more jolly, more good natured as a baby than his siblings, but I wouldn't tell them that!!
His speech is delayed, he is still trying to find words now but he signs very well and has always been able to make his needs understood. There's really a lot of resources and info available now to help children with DS with their learning. It's a good time to be around.
Please PM for any specific enquiries...I'm happy to answer anything I can.
You will cope, you will surprise yourself. A sibling will be a great motivator for your baby.
Sorry that's a bit garbled, back later x
