Kristie - Eden was 3.2 kilos when she was born and 48 cms long. I am not sure what length she is now but she weighs about 5.8 kilos now. I will measure and weigh her tomorrow when I take her harness off. YAY

It sounds like you know quite a bit about core body strength and stuff - do you have any other handy tips or exercises???????? Are you a trainer or something like that or have you done Pilates??
Went for a quick swim today - only did 6 laps as I wanted to get back to the kids but it went OK.
