So being a first time Mom I'm not sure if I'm overreacting.

I just went back to work from maternity leave so both me and my significant other work and our little one stays with his sister or Mom.

Well I go to pick her up today and I kind of get irritated.

I should add that she also has to watch after a 2 year old and an almost 7 month old that are her kids.

Anyway I get there and first off she can't find her nuk. "She has other ones right? I'll have to look for it".

Secondly we have the dr. Brown's bottles with that blue insert thing and she lost that too. Which I don't understand because the bottle and nipple itself were in the sink but the rest of it wasn't. So she said she'd have to look for that too. Also just getting home I realized that I'm missing a bottle which she probably has as well.

Lastly, she told me that while she was out having a smoke or whatever she was doing she thinks her almost 7 month old son might have thrown a toy at her because when she came in she was crying and that she didn't see anything but to make sure I see if anything pops up. What I don't get though is why she would assume that he threw a toy at her if she didn't see it. Maybe she could have just been fussy because she left. So do you think she was lying, and she actually saw what happened?

I'm just so upset and I feel like I didn't do anything because she's family and I didn't want to start shit so I told my boyfriend to say something to her so I hope he does.

I should also add she's 23 and seems kind of immature.

*adding also a couple of days ago when they watched her I think they might have left her in the car seat for a long time because when I took her out of it she had a red spot on the back of her head that I've never seen before whenever she is laid down. So I was kind of upset about that too. But my boyfriend got all defensive about it so I kind of let it go. His reasoning, "all her kids turned out fine"

Makes me want to quit and be a SAHM!
