I have a small bag that’s just too small as I can’t fit a nappy in it.
I have a nappy bag for day trips which I really like www.amazon.co.uk/gp/aw/d/B01NASOI1D/ref=mp_s_a_1_1_a_it?psc=1&ref=plSrch&keywords=miss%2Bfong%2Bdiaper%2Bbag&th=1&dpPl=1&dpID=41QqIGXRL2L&tag=mumsnetforum-21&ie=UTF8&qid=1518594992&sr=8-1 but is too big for everyday use.
I really want to find a bag that isn’t too big, isn’t too small. Fits wallet phone, a few toys and a few nappies. A crossbody strap is essential.
