What a great topic for new mums to be!

I have a large nappy bag which I only ever use if we go away or if I use the bertini pram. Generally I will use a small normal backpack with the stroller (popped underneath) and the bag that came with the pram over the handles. I also have a kapoochi small back pack which I use as a handbag. It has the bottle cooler/warmer thing and lots of compartments for little things, if I'm not going to be too long. So in Jack's nappy bag as well as the usual items we have:

a pen
sunscreen
bibs
hat
pegs (great for clipping a bunny rug over the pram or whatever, it holds it there well!)
tissues
face washers
balloons (not blown up)
food/water/rusks
a book
Jack's sunglasses
and always always wherever we go.......a peanut butter s/w! (for Jack)
