I,m an older mum too, I am 41yrs and have a DD23,DS19,DD10,and DS14mths. I feel the same, you remember some things but forget others,plus techniques have changed so much now. One thing i couldnt get over was how many differant sorts of things there was to choose from when buying stuff. I live in Sydney and would love to chat to other mums. Please feel free to PM me.
