Recently visited a friend who has a baby the same age as me (just turned one) and was surprised at how many toys they have. A full playroom full of loads and loads of lovely toys. In comparison my poor dd has one basket full of broken toys and torn up books. She isn't overly interested in toys and prefers to open drawers and pull things out or crawl around the house wreaking havoc. She has teddies, shape sorters, stacking cups, board books and a few electronic things like a pretend phone. But having had my house taken over with plastic crap from my older two I decided things would be more minimal for her and I wouldn't get things just for the sake of it if she didn't play with them.
That said I do feel a bit mean now, like she should have more. How many toys do your one year olds have? And what do they play with most? Obviously as she gets older and engages more with toys she will have more.
