There is no age limit when it comes to massaging a baby. You can massage your
baby as long as you want. It is preferred to give your baby a good massage for
the first year. As the baby grows older (s)he wouldn’t sit for so long and would
want to keep moving and running around so it becomes tricky to massage older
babies. If the baby likes and allows to get massaged you can massage him/her
till it's comfortable for you and the baby.
