My LO is four and a half months, he is sitting up and grabbing and people are always commenting about how alert and active he is for his age.
However everyday I put him on his tummy and try and encourage him to stay there by playing with him but he just smiles and rolls himself back over!
Does this mean he won't ever crawl? I am 18 and a first time mum so not really got a clue when it comes to baby development.
