If so, when did they grow to tolerate it?
LO never minded it THAT much, but all of a sudden he wants nothing to do with it! He's 9 weeks old. He yells and fusses as soon as I put him on his belly. He tries to army crawl/scoot by pushing off with his feet, but he can't obviously coordinate his arms yet, so he just slides his upper body along the ground, if that makes sense. He can hold his head up pretty well, but that doesn't seem to help. He yells the entire time, which usually erupts into full blown crying.
How long did you make your infant do tummy time if they hated it?
