Me and my DP have been together for 4 years. We have a DD age 2 and DSS age 5. We have DSS every weekend and more through the holidays. Any advice on who should be buying my DP birthday and Xmas pressies. I'm thinking it should be me to take both children out to shop for presents. But DP ex has other ideas and always wants to get him stuff which he does not need. I tried having a word with her but she thinks she should be the one to take DSS out to buy his dad presents. AIBU to think she should not be buying her ex presents even if she says it's from her son when it's clearly more from her.
