My son is 2 months old now & is getting stronger everyday! He's gaining more & more control over his head. He can lift it no problem, he has since about day 5. He's really starting to push with his arms & feet too to move. I have him still sleeping in the positioner but when should I take that out?

You can take it out whenever you want...Katie figured out how to roll right over it...and now is a tummy sleeper.
