Hi,Clare.
They don't need loads of toys.My youngest is 13 months.He likes balls,things to push along,although he can't walk yet he crawls after them.He doesn't have crayons,but I have seen him try to use his sisters' magnadoodles,ELC have a very basic one for babies.
I usually go to ELC first.They often have their own version or similar of more expensive brand names,and you know their toys are safe.They also have the age on them,you could use thast as a guide,most of their stuff is educational.Maybe a shape sorter ,playtray,perhaps something to build with,stacking cups,that sort of thing.One dolly would be enough,and maybe a basic but stable pram,you certainly don't need lots of toys that do the same thing.Maybe something to ride on.That sort of thing.
I try to have one or two toys that are a little ahead in case they show an interest.
Our ELC has a day each week when you can go and play,and they often have stuff out besides.Take your little one in and see what catches her attention.
