Actually DDIL was intentional and in my case stands for Dear. She is dear to me. We have a good relationship. I have no difficulties with her at all. She seems to like me and most times, when they are leaving our house, she says, "bye, love you". So, like I said, I don't really understand why the baby doesn't wear the things I buy, but I am not wasting any more $$.
Haven't read the rest of the thread, i just wanted to jump in here because it's clear from this comment that you care for your, as you say, DDIL.
It's a tricky transitional period right now, hormones abound, please please don't let a silly thing like clothes ruin it. If she's a brand new mum she's maybe directed you to brands and styles she thought she'd like but that aren't very practical. Or perhaps she's had a washing mishap and is afraid to tell you. She's there, visiting you with baby, sending you pictures, you are so loved in this picture. It sounds like she values you enough that if you just said, i don't know: "how did you get on with x piece of clothing, i didn't see it on much, did it not work out?" without any kind of tone or bitterness, just kindly like, she may tell you and then you can put it to rest in your mind, if you must.
