A hamper to share is great. If she had a key worker, a little poem and forget me not seed (look on Etsy) is a gorgeous idea x
Not quite what you'd probably wnat but... I saw a Facebook post the other day of a nursery who got a Tonies Box. They were raving on fb about how amazing this box was and how much the kids loved to listen to the stories and songs. They also asked if anyone had any figures they were looking to give away as they'd like lots more. But these figures are quite pricey even second hand.. You could potentially get the contact numbers of other parents, then all buy 1 tonies box and a few figures together for the class. Everyone would love it and maybe the classes can share it too. Plus can be used for years to come!
A hamper to share with biscuits, chocolate and tea/coffee, little treats might be good?
