I have a very large family so ds will get a lot of presents under the tree simply from family and friends.
His grammy alone probably sends around 20 presents, but these include clothes and small fun items. His favourite last year being a folding spoon that looked like a bug which is great for his lunch box and noone else has anything like it.
I do get him lots of things too, probably too much but that's my choice and I don't buy anything on credit ever. I save all year and buy stuff in the sale or BOGOF whenever I can. These include dvds, books, stickers, jigsaws which really aren't that expensive if you only go for bargains and special offers. I don't think of those as big presents though as nothing will cost more than a fiver, even for a dvd.
So yes, I'm afraid my ds is probably one of those children who will get around 50 presents under the tree. But they are not all from me and they are not all 'big' imo. He gets one main present which is from me, not Santa. Last year it was a digital camera.
Every year he gets to list 4 items on his letter to Santa. And every year he has asked for a sticker book and a jigsaw as two of those items. He will get more than the four he lists of course, but he knows there's only 4 he can choose and expect to get as Santa is busy and there are lots of children wanting gifts each year.
I do go a bit beserk on his stocking though. Hawkins Bazar, pound shop, bargain to be found in the supermarkets throughout the year if you keep your wits about you...
And when I look at the big expensive gifts available out there, I just remind myself of when he was 4 years old and he opened a present containing a green, star shaped, hot water bottle and he quite literally jumped up and down shouting with excitement. It cost santa all of £2 as I recall and he still takes it to bed with him on cold nights (he's now 9).
Everyone's opinion of what is a 'big' present or a lot of presents is different. I would say don't worry about what anyone else does, do what you and your family want, can afford and enjoy. If you get pleasure from giving your child a couple of gifts that they will love and use then do that. If you get pleasure from having a huge pile of tat (or not) under the tree then do that. We're all different and have different priorities and traditions. Don't be worrying about what someone on some other website says they do.
