Right away! I started laying my son on his tummy for just 5-10 minutes at a time when he was 1 week old. By 1 month he was already strong for his age and was happy doing tummy time for 10-15 minutes at a time. By 2 months he could hold his head for long periods. Waiting till 3 months is way too long to wait. I hear from alot of moms with babies my sons age who say that their baby cant hold their head at 3-4 months because the moms never had their babies doing tummy time. My son would cry when he was younger but I just kept doing it a few times a day. At 5 months he loves playing on the floor on his tummy and can roll both ways and sit up by himself. My pedi says he is strong. My sister has a baby the same age as my son, he never does tummy time because she picks him up right away when he wimpers. You wouldnt believe the developmental differences between the 2 of them.
