My little one is 18 months and getting very boisterous. I can't seem to stop him from climbing all over me and throwing himself onto me and landing on my stomach. I am trying to stop him from landing on me when I know he is going to do it but sometimes he just launches himself onto me. Do you have same problems, how do you stop it?, will it harm baby? Also how do you cope having to pick your lo's up and carrying them around? We are told not to lift anything heavy however my son is heavy and I'm constantly having to lug him around xx
