What should I do?? Part 2

So anyways once my sister in law found out she was having a boy my mother in law instantly started offering her our sons things. Now don’t get me wrong I have no problem donating things but she didn’t ask me she just said I needed to make a box for her and give her my breast pump. I was honestly taken aback by this like wow. But anyways I got over and I decided to make her a box full of baby clothes and another box which included a baby monitor, breast pads, nipple cream, milk storage bags, pacifiers, bottles, etc. so I did give her quite a few things plus a belly cast we bought for her and a cute outfit for the baby. Now I didn’t want to give away my pump because I plan on using it for my second baby and this seemed to kind of upset her (my sister in law) I told her she could borrow it but she would need to buy new tubing and return it once she was done using it. So fast forward to now... her baby shower is coming up except this women has been buying so many things already that I have no idea what to get her! I understand they’re excited and all but why not wait till after the baby shower? But anyways the thing is I feel like she’s expecting us to get her many expensive gifts. Despite all the struggling we did my husband was able to get an amazing job in which he now makes around 3,000 a month while I stay home with our son. Now using that to our advantage we have been buying things that we needed for our home for example: pots, pans, cutting boards, silverware, and things for our son as well since he is growing. My husbands birthday is also around the corner so he wanted a PlayStation and I say yeah babe treat yourself. Now when she came over she noticed all these things and said oh that’s good. But now we received a bill for tolls that $1,100 these tolls are literally 2 years old but we have to pay them or our registration will be put on hold on our car and we don’t want that. So we’re going to pay it off this month but we won’t have much leftover for our necessities and my husband won’t get paid until after her baby shower. I wanted to get her something nice like the bedside sleeper she wanted but it’s a little pricey. My husband told me we didn’t have to spend so much since we’ve helped her out more than enough and she never did anything for us. I understand where he’s coming from but I also feel like they’ll be upset because we didn’t get them something expensive. So we decided not to spend more than $100. So I thought maybe the high chair she wanted and some diapers with wipes. But like I said before she just keeps buying things and she has over 60 people coming and I don’t want to feel guilty because we can’t spend so much on her even if she hasn’t helped us.
