To return these gifts

[StripySocks1]

I know that this will sound ungrateful but it really is a bit overwhelming.

I get on with my mil but she an 'over-gifter' she always asks what my parents have given us for Christmas and birthdays and makes sure she gives more both in quantity of gifts and that she's spent more.
The thing is that my parents usually buy thoughtful gifts whereas hers are usually piles of tat.
I have spoken to her in the past about not buying so much but she always says she wants to spend her money on us now so she can see us enjoy it.
Recently she's been giving us loads of clothes and 2nd hand toys for our newborn, the toys are all obviously well played with and I don't want to give them to my baby, especially as she has so many other new ones from other friends and family and the clothes are really really not to my taste but I feel awful that they'll never get worn. If it was just one or two things I'd smile and put the baby in them when she's around but it's two or three new outfits a week and some are hand made.
My DH thinks we should just give them to a charity shop but I think we should give them back to her and say something along the lines of thank you for these, but we'd prefer to have fewer new toys than lots of 2nd hand and the clothes aren't the sort of thing we like but we can tell you which shops we like baby clothes from if you want to buy outfits.
I should point out that we aren't grabby, we don't want or expect her to buy us anything but we know that she isn't going to stop buying us things because it makes her so happy, on the other hand she won't take gifts from us and doesn't like receiving gifts herself (we still buy her gifts though)

Glitter Are you the OP? Your name has changed?

Ignore that, Glitter. I just saw your last response!

but we'd prefer to have fewer new toys than lots of 2nd hand and the clothes aren't the sort of thing we like but we can tell you which shops we like baby clothes from if you want to buy outfits.

Very hurtful and a bit entitled to say we will only accept clothes if you get them from x or y

I have an aunt who loves shopping in second-hand stores and then sends DD some really very obviously worn clothes which may have been good quality 15 years and 300 washes ago.
She also loves shopping in the likes of Tesco clothes sales and buys heaps of stuff that's been left on the shelf for a reason - mostly colours I wouldn't put on if I were paid for it. She has the idea that pastels and beige look fantastic on me and DD even though she's been told we don't wear them because we just look like we've left and the clothes are walking on their own.
She also buys pair of cheap shoes and sneakers which I have to throw away immediately and spends shitloads on money on sending the stuff over.
She also has the idea that our corner of the world is so warm that come May me and DD wear plenty of thin and airy blouses and shorts. Right, especially when it's 13 degrees and lashing rain like it's right now.
I told her many times to please not do it. I was even blunt with her and told her I don't wear the colours and neither does DD. Unfortunately, she's totally deaf to anything. She prides herself in buying bargains for us (which they aren't if you include the postage and the fact that they aren't even suitable for a charity shop).
I gave up already, take the stuff, thank her and it goes straight into the charity container, hoping that someone will find it suitable. She doesn't have lots of money and she's simply throwing the money she can't afford to waste away but at a certain point you just stop trying to persuade her otherwise. Especially as she can't bring the stuff back due to being second-hand and/or sales.

Thanks for all the replies, the consensus is that it would be hurtful to return them so I won't do that, it's not my intention to hurt her but she really doesn't take hints so I thought that might have got through to her that it's too much. We can't really say we haven't got space as we've got 2 spare bedrooms so it'll just have to go quietly to the charity shop.

As for those asking about handmade clothes, I love handmade clothes but by her own admission she's not very good at knitting and we are talking about 2 carrier bag fulls of cardigans in newborn size.

Piglet - the last thing I want to do is sound entitled, I'd just prefer she didn't waste her money so if she's going to spend it I'd rather she spent it on one thing we will use than than 10 things we'll end up taking straight to the charity shop.

How about droping into conversation about how much you love the clothes in the shops you like and how well they wash etc or take her on a shopping trip with you ?
