What us tummy time ? How to introduce that to your baby ?? My baby is 2 & half month old

A. Hai good morning !! Tummy time means placing baby on her tummy and leave for 5-10 minutes. This will help in roll over, holding head and crawling. As baby is 2.5 months old you can start tummy time daily twice while massaging or while baby playing for 5-10 minutes. Don't give tummy time immediately after feed as it leads to vomiting (spitting up milk), after 10 minutes of burping and also not more than 10 minutes at a time .
