I haven't counted, but I wouldn't be surprised if from Santa alone its as much as 30 each but that includes lots and lots of little items, such as flannel, bubble bath, goggles (50p in wilko sale!), choc coins etc etc. I have spent about £100 on each of them, so I have not gone mad, just got a lot of presents for my money.
My Mum (and Dad) do go pretty crazy at Christmas, and will prob get them more than me, but again, it will be made up of lots of little things as well as the main gifts.
Plus there are lots of aunts and uncles, and family friends.
I would hazard a guess at 75+, but I could be way out, in either direction.
