DS1 was 3.5 and DD was 2.5 when we had DS2. Life changes were:
1 New car - our estate car (would you believe it) wouldn't fit 3 across in the back so we got a Toyota Verso - a 7 seater and it's great.
2 DS1 and DD who had always shared had to learn to sleep on his own - he still misses her!
3 You don't have enough hands. A friend described it as going from man to man marking to zone defence - he was absolutely right! DS2 is now 2, and out of the buggy - it's a bit like herding cats!
4 It was easier to keep them entertained. The more there are the more they seem to just get on with it and keep each other busy. Although it does mean that DS2 is practically feral. And of course they're better at sharing and helping us around the house because they've had to be.
5 Childcare got massively more expensive. As did food bills and holidays. It also seemed to double the kid's washing which I've never understood...
6 It's noisy.
7 But it's huge fun. I can't think of anything better - except possibly 4 (but sadly we lost our 4th just a couple of months ago when I was nearly 21 weeks pregnant ).
It's only changed our lives for the better having number 3. He was the easiest to cope with and, yes, he slotted right in. I was worried about DS1 and DD being so close that he would be excluded but that hasn't happened at all - he's just very, very loved.
Hope that's helped. And FWIW I think you should go for it!
