I don't use a proper changing bag, I use a MASSIVE bag I got in Primark. It's like a heavy cotton/canvas, and had a palm print type thing all over it, they have several in different colours/patterns, and also plain ones. It's exactly like this bag, but not in leopard print LOL
. IT IS HUUUUUUUUGE
and more than big enough for a blanket, loads of nappies, a wet bag, wipes, a bottle, some food, my jacket, a toy or two, Rhys' cup, and some shopping and my usual handbag stuff. I'd have to worry about the pushchair collapsing before I worry about running out of space I think. It doesn't have sections, but does have a small inner pocket to hold your purse and phone so they don't get lost in the depths
. The straps fit nicely over my buggy handles. And it only cost me €7, so probably £4 or £5 in the UK.
They also have lovely weekend bags, like this in loads of different designs
for under a tenner.
