mum is super toxic

so my mum has good intentions but she’s asian and she’s so stubborn….i been telling her from the very beginning that i don’t want her to buy any baby clothes off shein because they are known to have chemicals in their clothes that can cause cancer. and i told her that there’s so many cute cheap clothes that she can buy from kmart, target & big w, tj maxx/tk maxx. and i told her that when i was around 20 weeks but she bought like 2 massive bags of baby clothes off shein that were worth like $300 all up and once it came i told her i dont want it…but i told her im so grateful and she got upset of course so i had to just play it off and say i love them to make her feel better… but i made sure to make it clear that i dont want her to buy any more off there & i wont use it. i even told my dad and partner to tell her and they did & she said yes okay she wont. so fast forward im 37 weeks pregnant now and she gets another packet but from temu and there’s more baby clothes and i got upset and said mum i already told you i dont want clothes from there and she got soooo mad at me and called me ungrateful and she said she’s not going to buy anything ever again for my baby…and blamed it on me that she spent all this money on the clothes when ive even telling her from the start that i dont want it so i feel like its not my fault that she’s lost all that money on it?? am i in the wrong???? idk bro i feel like complete shit because she makes me feel ungrateful but i seriously just want to have 100% cotton and organic clothes for my baby…. idk what to do… the clothes she bought are also super cute but just full of chemicals which just sucks 😔
