My LO is 5 months and im a little concerned over his development. I have a few mummy friends with babies a similar age and their LOs are all over the place. They grab, kick, sqirm, bounce, roll, are strong on their legs etc.. and my LO does very little. Infact the only things he really does are lay on his back and kick and he can now sit up quite steadily. Im just a bit worried that at this age he should be doing a little more? He isnt rolling over either. He is the biggest baby out of the others and i dont know if this is having an effect. Or is he just lazy? I was determined not to turn into a mum who compares him to other LOs but its hard when you think there is a problem.
