When to remove baby mittens and booties?

In Singapore's erratic weather, there isn't an actual need for babies to wear mittens or booties. It will cause much discomfort and I've read that it can hinder baby's basic motor skills like holding or gripping items. If you're worried about babies scratching their faces, trim their nails whenever they get too long. Moreover, mittens and booties tend to go missing a lot as the babies will find a way to remove them haha.
