Talk to me about Tummy Time.
F is almost 12 weeks but he hates it. He lies with his face on the bed, mat, whatever and tries to push himself forward with his legs! He can lift his head and turn it to the side with apparent great effort even though he has good head control when sitting on my knee. If I put him over the playnest he will lift this head. I have I affected his development but not persisting with tummy time?
