What do you buy for a 1 year old?

My daughter is turning 1 in a month!

She’s got everything! We’ve got blocks, plush toys, rattles, books, security blankets. She’s even got a little toy piano which she loves to smack.

She has so many clothes that she’ll have outfits until she’s 2 - most are hand me downs and some are very nice.

At this stage I’m just going to get her a colourful birthday cake and let her destroy it. I think that will be fun for her but otherwise she’s not going to remember this birthday at all so I’m a bit lost as to what to do for her.
