My 16mo dd has been walking for 3 months now and I got her proper shoes about 6 - 7 weeks ago. She walks a lot in her shoes. How am I meant to know when her shoes are too small & she needs new ones? Ok, so when I can't get her foot in, it's a clear sign, but surely they'll be uncomfortable before it gets that bad. How often do you need to get new shoes for your toddler?
