We spend (about) $100 on each kid (less when they are younger) for Christmas - and that includes their stockings. We all have stockings, and in those goes the junk type stuff - a bottle of drink, some lollies, a small pack of chips, a chocolate bar, an orange (family tradition) and two or three small ($2 shop) fun things. Everybody gets the same sort of bits and pieces.
For our kids, we get them one big present from us (last year Kiya got
Good Morning Sunshine and Josiah got two or three age appropriate toys as he was only 7.5 months old). We also get them a bunch of smaller things as they are still at an age where quantity is what counts. Nikki - Kiya gets a box of chalk just about every year! She loves it!
Xavier isn't going to get much from us this year... he's not going to be more than 5 weeks old, and doesn't really need much! We're going to get him a nice outfit to wear on the day, and maybe something else. He will be grandchild #3 for my parents and #8 for Nat's parents... and all my aunts and uncles (and some of Nat's) buy for our kids too - their choice - so he'll get lots anyway.
