My daughter is 4 months 16 days old. What can I do to relax her when she always wants to lick something???

A. Hello good afternoon !! New born babies always want to latch ,give frequent feeds every two hours and burp well. If the baby wakes up in the middle and wants to latch then give feed on demand and make them sleep but don't give any pacifiers. Rock or gently pat on the baby shoulder to make them sleep.
