Homemade biscuits are a nice idea, you could cut the biscuits with biscuit cutters in cute shapes like: a teddy,or small animals; using small currants for the eyes and hundreds and thousands or chocolate hail for decoration.
Baskets filled with little gifts for the mother and baby are always appreciated. You could include such items as: small soaps in sweet shapes, hats & booties, cosy blankets, small teddies, rubber duckies, and natural baby shampoos and lotions.
