My daughter and SIL are flying to another continent with their toddler on Boxing Day. I've already bought their main presents but wanted to get stocking fillers they could take with them. The adults are early thirties and the toddler is 18 months. Does anyone have ideas for small items? I was thinking of things like face masks, that could be packed easily, but I can't think of anything for the toddler apart from books, and I think familiar ones might be better there.
