When my 15mo DS gets tired or excited, he hits me/DP and laughs, or throws things on the floor laughing, and when I say no or dont do that, he 'says sorry' to me/his daddy (as we are the only ones he hits) by laying his head down on us and patting us better.
If he sometimes accidentally hurts his friends (he knocked a friends child over by giving her a cuddle and she cried) or they cry because they don't want to share or he knocks DP's glasses off or what not, he gets very upset and will immediately go to the person and do the same 'sorry' action. The difference is that he will not do it again in that situation. But with the tired behaviour he seems to only do it so that he can say 'sorry' to us as hes doing it again within 5 minutes.
I could of course illuminate this by not letting him get over tired but we don't live in a perfect world. And is this even normal? What do people suggest I do to help?
