... A great thing, just drop these things unfortunately extremely small. Did the birth of our daughter initially 0-6 months variant held in hands. This, however, was so close that I did not dare to squeeze their tender feet in there. Have then started almost immediately with the 6-12 month size and does its job great, but now with 3 months also disturbingly tight and we only use them with thin socks. Lange is unable to walk but even that. Would not even want a size "18-24 months", which we can use from 4-8 months or so then;)
