Shoe size for 12 month old

Anyone care to guess a shoe size for our 12 month old girl? On her last update (almost 11 months) she was 29 inches tall and about 22 lbs. She was wearing 12 month clothing. I want to take her some shoes on our upcoming visit trip, but am a clueless first time mom. I have bought a couple pairs of 5s and a couple pairs of 6s. Does that seem right? Thanks for the help!
