DD's Be My Bear Party was her most successful one and I received thank yous from the parents because the DC had enjoyed it so much. Especially the boy I mentioned earlier in the thread.
I thought I'd share my party plan for you OP, in case it's helpful. We didn't decorate T-shirts to keep the costs down and I printed off birthday cards to colour in instead.
Be My Bear Party
On the floor on a rug in a circle each child stuffs their own bear with help from an adult as needed. When everyone is ready (adults check bears are full stuffed), everyone makes a silent wish and puts the wish in the bear and close.
Tell the children they now have to think of a name for their bear. Children make or colour in a birthday card (print off copies beforehand) for their newborn bear writing inside To Name, Happy Birthday, Love Name.
Teddy bears picnic on the floor with mini food. Eg. Mini Jamie dodgers, mini chocolate fingers, small squares of pizza, fries.
Move to the table for cake time. (We removed all the chairs so they could stand around it). Table had DD’s birthday cake in the middle and each place setting had a fairy cake with a single candle in it. We sang Happy Birthday to DD first, then lit the single candles and sang happy birthday to the bears (each child singing the name of their own bear) then blow out their bear’s candle.
Then play pass the parcel with the bears included in the circle. Prize is a T-shirt for the bear. Could play other games with other accessories as prizes.
