just another thought folks, how many kids will be in on xmas day? and how will you know the age groups.
here is an idea for you:
boys - scooby cars, various sizes etc dependant on age.
girls - barbie dolls or similar
babies in icu - teddies, as you wont get much into an incubator.
hopefully this sounds good to you all, as boys do like cars and girls dolls. as i say only an idea.
