1) which was harder, going from no children to 1 or from 1 to 2?
1 to 2, definitely. Largely because I found my second pregnancy much harder work (impossible to rest as much when you have a toddler), and I had pre and postnatal depression, which I didn't get with #1.
2) did having more than 1 child put more pressure on your marriage?
No
3) what is the age gap between your kids? Would you have preferred if you had DC2 sooner or later?
21 months. It's fine - bloody hard work for #2's first year, but now she is 2 it's starting to get really nice, they play together. #2 was a miracle natural pregnancy, but we were hoping have a gap of around two years, if a second was possible.
4) for those mums who BF number 2, how the hell did you do it?!?
I fed both mine for a year. #1 just had to lump it! Similarly, #2 had to lump it when we went to toddler groups etc. The world did not revolve the newborn in the way it did for #1. When #1 was napping it gave me and #2 some time alone together for feeds and cuddles, which was good.
5) did you need your partner to be more hands on once the second arrives?
This implies he wasn't hands on with #1? He's no more hands on with two than he was with one, but then he's always been as much of an engaged parent as I am anyway. He looked after me more than he had/needed to with #1, but then I was suicidally depressed with PND for the better part of a year, so not really similar circumstances.
I am so grateful for my two girls. Youngest is currently a stroppy two year old, but I love them both dearly, and love how much they love each other. It is a huge joy to see my children enjoying each other's company. Having a relatively short age gap does mean you are over the difficult early stage more quickly, and I find that my kids enjoy the same sorts of trips out and toys. I imagine a bigger age gap would mean one was often compromising for the sake of the other.
