Ladies I need to vent.. sorry it's long but please help me out!

Let me preface this by saying that I love and appreciate my mom and everything she does for me and my son.

I'm due with my second baby in January. Because it's my second, I didn't (still don't) feel like it's necessary to have a baby shower, even though this one is a girl.. I told her this multiple times. We have my sons first birthday at the beginning of November, so we are going to have that, and there's Halloween right beforehand then thanksgiving, Christmas, and New Years directly after, and then the baby is due. I felt like it would be way too much to have all those get togethers in that short span. She pressured me into it and told me she'd plan everything and I wouldn't have to do anything for it. Now she keeps messaging me with questions about things and wanting my opinion. I appreciate that she wants to please me but I didn't want this in the first place. I feel like it's more for her to enjoy and I'm doing it to make her happy. She's also continuously buying my son clothes and things and i feel like I haven't had the opportunity to get things for him myself because she gets SOOO MUCH and by the time she's done, he doesn't need anything else. I mentioned getting a pair of shoes for him and immediately she went to target and started sending pictures of all the ones she found and thought would be good for him. And she's already starting for my second baby as well. I want to do things for my kids and feel like I'm providing for them. Right now I don't. It's super frustrating and I don't know how to approach it because I don't want to hurt her feelings or make her feel like I don't need her.

I'm just exhausted trying to get school started again so I can finish my degree, making plans for our future with my husband, planning for the new baby, getting my sons first birthday put together, and I feel completely under her thumb with everything. Everything I do or don't do, she texts me saying have you got that done yet or did you do this and I'm tired of it. I need space!!!
