DS is turning 3 in December. His birthday is the week before Christmas. We typically don't decorate until after his birthday decorations come down the day after to let him have "his day".
We spend £150 each per child for Christmas and £200 for birthdays. It just so happens that DS being a December baby has a full on December with activities, his birthday and Christmas. But my sibling is constantly making digs about him being spoiled and having too many toys. SIbling had more toys than my DS has at his age (and more expensive too). I disagree DS actually doesn't have a lot of toys as we are conscious of plastic tat and prefer wooden toys so tend to buy less and sets the kids can play with together like a railway set with extenders and buying accessories occasionally. Also I prefer to save for DC instead, so always put away the money into savings when I am tempted to buy something unneccessary.
Sibling's argument is how last year he got a bunch of presents then a week later he had even more toys for Christmas. It was his birthday and Christmas FFS! He is 2, sure he may not mind now having combined gifts for Christmas and his birthday, but I am a firm believer in people repeating patterns. That's why I insist on treating all DC fairly from the get go because once you start the 2 in 1 gift you are likely to repeat it year after year and even when they are old enough to mind and see they are being treated differently from the other DC.
I may be a little sensitive to this as I was born in January and often had the combined Christmas/birthday cake whilst my siblings born earlier in the year had the full on birthday thing, but noone could face another party/celebration after Christmas and everyone's budgets were too tight after Christmas to buy presents for me. DS has siblings born earlier in the year so its only fair he gets the same treatment right?
