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 the baby's hands and toes for longer, it will be difficult for them to move their hands/toes. 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 them warm.
