DD1 & DS1 were about 2 1/2 I think when we ditched theirs, I did keep one in the cupboard for ages JIC but we never needed it. Pretty sure we just went with 'you're too big for that now', and I think one of them gave them to the baby animals (not for real )

My sister gave hers to the baby kangaroos, and my other sister I think to the Easter Bunny or something similar. Maybe you could aim for Easter? It gives her a couple of months to get used to the idea.
