DS currently 22 months. Lots of chatter that's not entirely clear - though I do decipher the odd word or phrase (I'm sure no one else would though) and then odd words here and there. Things he likes, "drink" "car" "Cat" that kind of thing, "stairs" "ketchup"
He's occasionally given to minor tantrums, esp if he's tired and or hungry. They're not severe and they don't last long. He doesn't hit and he doesn't hit back when other kids his age hit him, he backs off and if they hurt him, he runs off. But he's generally quite happy, still interested in pans and books and very interested in other children. He wants to play now, to run and chase and laugh in the park.
He used to be impossible to get out of the bath and recently I've had a real struggle getting him into it.
He's started waking in the night sometimes (never did before) when there is a noise or if he's got cold and needs help with blankets etc. This is phasing out (I think!)
He can eat food himself but likes to be fed if his baby sister is being fed. He understands that he has to do it himself and with some pursuading will do it.
He likes to sit on a big dining chair instead of in a high chair.
I have friends with boys the same age, some are getting a bit aggressive. I think they all try and throw themselves over the side of the sofa (mine too). I did read that there are surges in testosterone at various stages, particularaly with 4 yr olds.
Oh and he's lately found his willy. I think later than other boys who I've read about on here.
