My baby is so unhappy, and it seems lazy, when i put him on his tummy He just either smushes his head into the floor, or turns it to one side and lies there whining. He is not interested in pushing himself up at all. I have tried putting toys for him to look at, I've tried helping to prop him up. I dont know what to do to get him to have tummy time. I know there are play mats out there designed for tummy play with like a circular cushion in the middle, does this work, we already have a baby einstein mat and i dont really wanna spend money on another one.. any suggestions? p.s. i try put him on his tummy only when he is in a good mood, not hungry, or tired.
