When to remove baby mittens and booties?

A good time would probably be around 1-2 months or so! Reason being, they need to exercise their little hands and feet - using them to explore textures, train motor skills etc. Most parents are afraid of removing in fear that they'll hurt themselves, but all you need to do is to trim their nails a little more often - if LO moves about too much, you can do the trimming when he/she is asleep or drinking milk :)
