Mason has just turned 4 months and he will not tolerate tummy time at all! I try every day to increase the time, but he screams bloody murder!! I can get about 1-2 min tops out of it. I've tried everything under the sun to get him to enjoy it but it doesn't work.he holds his head up but screams.Not cry-screams! He's got reflux but I do it when hesin a good mood not around bottle feeds etc. how is he supposed to crawl or turn over if he can't even do this?!
