Unreasonable to ask DM to stop buying my kids clothes!?

[Somanyusernamess]

I was a single parent with DS and although I didn't struggle financially I think DM wanted to feel like she was helping out and she would buy alot of clothes for DS over the years, I was always grateful and would tell her she didn't need to etc.
Fast forward quite a few years I now have DD, i have a DP now and we do not struggle for money.
My DM has gone into overdrive with buying clothes! I know the choice for girls clothing is so much more and that isn't helping but she buys at least an outfit a week! We have DP's family who also buy clothes but more sensibly e.g birthday and Christmas. And then to be equal she buys DS an outfit each time she buys DD one.
I an not ungrateful for it but 1. It's excessive and she wears each item maybe once or twice then grows out of it and 2. It's preventing me buying things as when I see a lovely outfit I think to myself does she need it with the extensive wardrobe she has back home. Her wardrobe is easily 70% clothes brought by DM.
Am I being unreasonable to tell her it's getting too much?
I have told her to stop but perhaps need to be more firm!

Maybe just next time she brings one say you want to get her some stuff yourself but you have no space in the wardrobe and could she dial it back a little bit.

Either return it to the shop, or take it, tags on, to the charity shop.

What did your DM say when you told her to stop? Did you explain why at the time?

Charity shop. My auntie loves buying our baby clothes (she had all boys) and half of them I don't like so to the charity shop they go for someone else to appreciate them. The ones I do like I take pictures and send to her with lots of thanks, she buys that much she would never realise half of it never makes it on to the baby and it brings her joy so I don't want to upset her

Say thanks for the lovely outfit, I am operating a 1 in 1 out policy now. And hand her a bag full of clothes to drop of at the charity shop. She might get the point that she's being excessive.

Maybe you could gently explain that as lovely as it is that she wants to buy so many things that they just don't get used. Think of all the money she's spent on clothes that could've gone into your children's accounts. It's just a waste. If she really feels like she needs to keep giving then suggest opening up a savings account. If she just like shopping them just gently ask her to stop as she's just not getting chance to wear all these clothes.

I've been in a similar position and it is difficult not to cause offence. Would she be receptive to you making an eco friendly argument for not causing so much landfill. It is criminally wasteful to buy clothes for use just once or twice. You want to teach your children the right values and they are getting the wrong message as a result of her lavish interventions.
