Little feet love EMU Australia baby booties. With sizes for newborns up to 24 months, your baby can grow with EMU. Designed for the youngest EMU Australia fan, their baby booties are lined with natural Australian Merino wool to keep feet warm and comfortable no matter the season. A velcro side tab provides ease when putting on and off. 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.
