I had my daughter in December and it was awesome. We had cold weather the first month that I didn't go out much anyways and after that it was easier to go out.
Right now she's starting to move around more so less clothes is great for that. I do NOT want to be in the third tri in the summer here. It's hot enough even when not pregnant!
We're going for a May baby next time, mainly because we already missed next December, and summer would be great for maternity leave, to be able to be with my daughter as well instead of finding some kind of arrangement for her.
But I am fully aware that when it comes to babies, you can only plan so much LOL!
