I can not get on with using a normal handbag as a baby bag?? I also am at odds with others who say you do not need much in a bag - I do!! I don't carry a bag for me so in my bag I have nappies, wipes, sacks, cream, fold up change mat, 2 bananas, 2 apples, few other snacks/rice cakes, my purse, keys, phone, tissues, lip gloss, mirror, small hairbrush and toggies (dd's hair very long)hand gel, sunglasses for all and winter/summer hats depending on season, spare gloves as dc's loe for a past time, bag clips, fold-up shopping bags, little first aid kit (wipes, plasters, cream, ambesol for teething, calpol sachets) and drink for dd and ds.
I like a good size bag that is waterproof inside, not too heavy it breaks my back, big enough for mornings. We walk everywhere and so many times dd falls over on the way to playgroup I go through plasters like there is not tomorrow. The shopping basket of my pram is full of shopping as I get things as I am out each day I don't do a big weekly shop.
We are all different, I could not possibly manage by stuffing things in a normal bag (nor would I want to ruin a lovely leather bag by a leaking drink of blackcurrent squash) so I do suit a change bag. When I don't need nappies any more a handbag will be fine but until then I like my baby bags!!
I love storksak, babymel (they are cheaper ones made by storksak) and pink lining. The free bag from Boots is not for me but couln't care less if everyone else uses them!!
