Am I being too sensitive about Christmas presents from family or am I just a b***h? 😂

I totally see where you're coming from, but I also don't think anyone is obligated to follow a list, no matter how much better that is for everyone involved. People can be funny about gifts, some think it's rude to even make requests and it's normal for people to just expect gratitude, so it's not necessarily coming from a bad place. With my list I tailor the budget and I also try my best to give open ended requests- rather than just asking for a specific thing, I choose something that they can put their own spin on. For example I wanted magna tiles this year so requested them but not a specific set. With my dad the budget tends to be a bit bigger so for Christmas last year I requested a "big thing" and then we were free to get our own "big thing". Maybe they don't like what you're requesting and that's a factor? I'd definitely try to have a conversation about it though because like you said it's ridiculous having multiples of everything, maybe a compromise can be made...

Well my mil didn’t even call when my lo was born so….

Kids are 9 months 13 and 15 and have never received a birthday or Christmas present!

Different families have different ways. I understand why you’re annoyed but my family wouldn’t normally ask unless they are stuck but my inherited English family (my husbands ex’s family) ask what they should get her.

IMO I’d tell them I’d hope they kept receipts as you’ve already bought them it!! Tough tits they’ll ask next time.

It's not the worst situation to be in. You're even lucky to have a grandmother who would be willing to go all out like that for your babies.
In the grander scheme of things this isn't going to matter. If she love them, treats them well and doesn't disrespect anyone, what she's doing isn't a bad thing imo. Grandparents are just as excited about these things as we are. In my case my mom has bought a lot of my babies "firsts" and although I have felt my opportunity to do that was taken I also see the joy it's brought to her, my baby has given her purpose in life again, she has a new little person to love and that's more important to me than the way I feel about buying a first gift, which may I add, I haven't thought about since that first time I felt a bit annoyed for a moment.
Let them also enjoy this time but as Karen above mentioned, next time they're likely to ask. 😊

Probs fuelled a bit by dislike for MIL but I’d say grandparents will spoil if they want to and everyone has a different attitude towards money / material items. If it were me I’d say Thankyou and then sell anything we don’t use on Vinted to go towards buying stuff I wanted to get for baby 😂 especially if it’s big things brand new that you don’t need! Find opportunity in the situation and you’ll feel more in control xx merry Christmas

I don't know if you're necessarily being a bitch, but I get the resentment. It's annoying when people don't listen or respect boundaries.

I had an issue with this in a previous relationship with my mum. I dated someone who already had a 10yo. She was told Christmas presents were fine, but only a couple and nothing too expensive (because my ex didn't want him spoiled or have his own family shown up). Instead of listening, my mum treated it like a competition and practically got him more presents than everyone else combined. It created so much tension and resentment for no reason other than her ego 🫠

For my own kids now, if there's anything big or specific I will be getting them I let people know. Then give everyone else open ended requests (like the eldest loves cars and trucks right now, loves bluey, is X size clothes, can never go wrong with books or experiences (even non expensive things like sleepover at grandparents etc)).

Like others said, if there are any duplicates, I would exchange/sell

I am so sorry that you have to experience it too. It is very annoying that mother in law tries to buy as much as possible. I could see it as overcompensating her absence. Some grandparents want to be important. The presents is the way to put themselves in the spot light.
I am not sure if she is even thinking about you or your child.

Thanks guys appreciate your views. I will try to get over it 🤣

I have a vaguely similar thing although not my MIL and it does annoy me that people overstep boundaries without asking. I won’t go into specifics but people doing or buying things that should be for the parents to do does especially irritate me.
Maybe I’m petty but I’d buy the stuff anyway and politely suggest that they should’ve asked you as you already have it so they’ll need to return theirs. Unless they’re pretty static things like bedroom furniture or something and spend equal time at both houses, there is absolutely no need for 2 of anything
