My daughter loves the following:
Babies (she has a few 'basic' babies but is asking for three more for Christmas!
Play make-up
Drawing
Peppa Pig
Princess dress up (her favourite birthday gift was a pair of play heels)
Building things (she has mega blocks but any other recommendations)
Cars and work tools
Any recommendations that might fit the above or any other ideas of toys your three year old loves. She has tablet and yoto and lots of games.
