Interesting. I have heard lots of people that its in hindsight that they notice things. My DS doesnt display those tihngs but as I mentioned earlier, he does other things that are concerning. I met up with a whole bunch of bubs from Mothers group today. He seemed pretty on par with the babies apart from not babbling that much and not paying too much attention to the other babies. To be honest though, no babies were really interested in each other so that didnt concern me too much. I took him to the park this afternoon and put him on the swing. He loved it but doesnt hold on, just sits like a blob which is a little weird.
