DH bought me a new bag a few weeks ago and I absolutely love it!!
Before that I used the bag that came with our buggy which was big and black and not very exciting. It didn't have many compartments either.
Or if I was only out for a short while I used one of my bigger handbags with all the baby things stuffed in.
It took me ages to find everything though because it was all in one big space..
My new bag is the Fanci Free circles in motion. I really love it so much! It looks good so I don't carry a separate handbag. And there are so many compartments I can have everything organised (my stuff and Matthew's) and find it again really quickly. It even has a wee mini wet bag which holds one nappy! Love it!
