I think my oh wishes I would start nesting. I didn't with my son, but I was working right up until the end because I'd planned to start maternity at 38 weeks, and he was born at 37+2. Now I'm a SAHM I'm more tired now at the end of the day then I was while I was working. Think that has to do with having a 3 year old who is on the go constantly for 12-13 hours a day, and won't let me have 5 minutes to do the washing up!
Good luck with potty training, I've given up trying to potty train Sebastian at the moment! He's getting better, he will willingly go and sit on his potty, but only if he's got his nappy and trousers on!
