Would you be offended?

I would not be offended. My in laws are not my parents. We simply do not have that kind of relationship. They're my husband's parents, so it makes sense to me that they would buy him stuff. However, how you feel is never wrong. So if you are offended they left you out then your feelings are valid and you should say something to your husband about it and he can address it with his parents about not leaving you or any other family members out in the future.

I'd be annoyed to, but honestly this is something my MIL would also do lol. Everything is about my husband, unless something happens she doesn't like...then it's my fault hahah. You should definitely feel ok speaking to your husband about it, but personally I wouldn't make it a big deal. There's other way worse things. Maybe just suggest to your husband next time that he purposefully buys some things for you too so your MIL gets the hint hah.

It sounds like she loves her son and is proud of the father he is. If you want a similar experience you should ask your parents about it. If nothing else I’d be happy it wasn’t our money being spent on a shopping spree and that we’d be able to save it for our family.

I would 100% expect this from my husband's family but that's the relationship we have. My family is different and would buy both of us things because he is just as much their kid as I am in their eyes. My parents see him more than they see me. But unpopular opinion here....I'd be annoyed at my husband. He isn't the one that A. is turning one and B. had the damn baby (unless he's stay at home or whatever). But my husband would pick out stuff for me/the kids when with his mom if she did this. Also unpopular opinion here but I think that adults getting shopping sprees when they have kids is silly. That's not to say you can't be treated or treat yourself but a whole spree is silly to me.

Kinda weird but if they want to spoil my man that's okay by me!

No I wouldn’t be offended and I agree w Rachel.
