can i cover my baby's hands with mittens till 6 months   

Experts advise that mittens should ideally be worn till 6 weeks. If you keep mittens on your baby's hands and toes for longer, it will be difficult for the baby to move his hands/toes. Your baby needs to explore and will need free use of their hands and toes, which is important for developmental purposes. You can put mittens on at nights or when the baby is sleeping to keep him/her warm.
