if they are tea drinkers then tea bag holders are great for them. there is a tut on here also. for the little girls, if they are into dolls then maybe a couple of doll quilts. for the baby a very simple play blanket maybe. for the older ones it just depends on where their tastes lay. I have a similar problem. I have three nieces and one nephew that I see maybe once a year because they live in Cali. ages ranging from 15-2ish and there is a new baby on the way in spring. For the older one if they are into reading and writing maybe a journal cover and a gift card to a book store or maybe make the kleenex holder for the gift cards to places that the kids really like to go. I would just go with your gut of this. it helps.
