When should I start tummy time?

you can start it the day the baby comes home (:

now, with just a few seconds at a time :) or you can lay baby on your chest that's tummy time too :)

I started with my daughter after about a week

I started the first week because she was already lifting her head at two months she has great head control

I've just gotten to the point where I can pick him up without supporting his head, he's still a little wobbly though

I started week 2

i really started after the umbilical came off
