I have no idea if this is the average age for him to do this, or if he's behind the average or ahead. In all honesty I don't know if I want to know. Of course I want to know if he's developing properly and would like to pick up on if there are any problems, but I just don't like the idea of comparing him to a statistic. I don't know if I'm just being funny or if other mothers feel the same. I just think he'll start to do everything in his own time and when he's ready to. While I'm sat thinking about it now though I have found myself asking others when their baby did what, but that is usually about when they started sleeping through the night (I miss my sleep!). I'm undecided if I will read up about it or not. I would hate to hear myself say "the books say he should be doing this and that by now"
I honestly don't know if these are common feeling that parents have or not. But this is just my personal view on the matter.
I will write down when he can do what, because I think it will be nice to look back on, and know exactly when he did each new thing.
Before the big roll!
