I'm a first time mother & just constantly anxious about my 18 month old son. I don't know if I need to be. He has just started running (been walking 8 weeks), can wave but rarely does wave, scribbles, points loads (& will point to body parts), makes towers out of blocks, has just started putting two lego pieces together, and loves being read to. If I say "where's X?" he'll often point at it in a book, but he only has a couple of words (not easy to understand), had a couple more but has stopped saying them. He doesn't do two-word sentences. He does pretend to be on the phone & feed a soft toy (but doesn't seem attached to a soft toy at all, doesn't sleep with one.) He won't drink milk out of anything but a bottle, and barely ever eats with a spoon; he throws a lot of food still. He likes being in playgrounds but just wanders around, very occasionally goes on a swing or if I put him at the top of a slide will go down it, but doesn't climb anything really, doesn't go up the steps to the slide. He doesn't shake his head for no. He doesn't copy very much. His sleep is not great (never has been) & I still feed him to sleep (nothing else works). I don't know if I'm worrying unnecessarily, but I can't seem to stop...
