Thanks for the new thread and the spreadsheet, Gimble. I've added my details there.
Just got back from a holiday in Wales. It was lovely to have time with DH and DS and in such a beautiful location but so exhausting, mostly chasing 21 month old DS round the soft play, indoor activity centre, beach, swimming pool and playground. He loved it so much but got filthy enough to need at least two outfits a day and his potty training took a big step back too. Not fun with cloth nappies/training pants and no washing machine! At least today he's been better with three wees and four poos in the potty and just one wet accident in training pants when we were in the car. I really want him dry in the day completely by the time his brother turns up so I don't have to buy any extra nappies!
I think I need to work on him staying in his own bed too, as a new baby waking for changes and feeds is going to disrupt his sleep a lot if he continues coming in with us when we go to bed. He enjoyed sleeping in a big boy bed (single mattress on the floor) on holiday so we are going to convert his cot to a toddler bed this weekend, I think, and settle him back in that when he wakes up.
