My DS is 5 and never spoken. I'd love to hear his voice but then I hear peoples kids repeat 'mum, mum, mum, mum, mum' and I look and smile at my quietly very wise and not annoying DC
Obviously, I'd rather he speak but some children have a great talent and getting me to appreciate what I have!
DD is not however disabled so far as I know, I'm sure it's coming with her 
Newborn babies are a bloody breeze. It is the easiest stage, absolute bliss. Babies in general fine. It's when they start walking and they're into EVERYTHING with no sense of danger. Sigh. Very tiring. Sadly for me DS is still like this now at 5 due to special needs
Oh and poop smearing. It isn't a special needs thing alone. Friends with non disabled DC tell me there's have down it too. Bloody annoying. Not even the smell but knowing where to start when it's CAKED on them and showering down to start won't work, but baby wipes won't cut it to start with. Arghhh
Teeth brushing. That's a bloody pain in the arse and another relentless couple of minutes I'll never get back
When you have 2 DC, you're never 'done'. I use to put DS down and feel done for that day. Bliss. Then DD came along and she stays up later because she's a baby. So once he's down the sigh of relief is replaced with '1 down, 1 to go'
The washing. The bloody washing. How can 2 small people have me doing so much washing?! I have to stay on top. I put 2 washes on a day for a family of 4. I went into hospital for 1 day with DD recently and I was then not up to date and it seemed to take ages to get on top of. After missing it for just 1 day! And no I won't ask my H. He can't be trusted not to put whites in with darks
