When do babies lift head?
Everything that happens with head lifting between birth and 3 or 4 months of age is a warm-up for the main event: the major milestone of your baby having full control of their head. By 6 months, most babies have gained enough strength in their neck and upper body to hold their head up with minimal effort.
How long should baby do tummy time at 3 months?
Aim for around 20 to 30 minutes a day of baby tummy time by the time he is 3 or 4 months old. Then keep the practice up until baby can roll over on his own, a feat many babies accomplish around 6 or 7 months of age.
