I do tummy time on my chest from day one and now on the floor about a little over a week and a half ago so when he was 3 weeks

My son was almost a month old when I started tummy time.

You can start as soon as you all get discharged. It is best to do it early

My sons doctor told me when their umbilical cord falls off is the best time to start

The sooner the better I would say. It takes them a little while to learn to like it

The sooner the better. The muscles need to develop. Baby wearing and on you chest counts as well.

We strted at 3 weeks. though she is just now starting to like it at 6 months.
