When is the best time to put my child in a walker?
Never -- I can't really recommend them for children of any age. Walkers give non-walking babies the ability to "drive" (without a license!). Without constant supervision, however, young children risk injuries -- falling down stairs or ending up in places you don't want them to around your house. As for toddlers and older children, they usually don't enjoy walkers since they already know how to get around independently.
