EMU Little Creatures are the best! Warm, soft and comfortable plus fun for little explorers. This little ladybird is a favourite. Designed for little ones learning to walk, these Ladybird inspired Little Creatures Walker booties are built on a flexible moulded rubber sole which allows for greater freedom. Plush, natural Australian merino wool lining keeps toes warm and comfortable. Here's some help with sizing. For the new born, up to 6 months, go for 6M. For those 6-12 months try 12M, then for 12-18 months, choose 18M and finally 18-24 months is 18M+. So you baby can grow with EMU! Of course, this is a guide only, as some babies can be a little smaller or bigger than the average.
