To jump or not to jump?

By some definitions, my baby is an infant at 2 months old. We got him an Evenflo exersaucer and a Pop! jumper as well as a batmobile walker. He is crazy active and we're doing tummy time until he gets a bit stronger.

Found the Evenflo Exersaucer on the left abandoned at the curb, so I washed it with dishsoap and water and changed the batteries and it's good as new. Had to order 2 new feet for the arch and a new spring for one of the legs, but I feel good upcycling something that would have ended up in the landfill. The Pop! summer jumper was $60 and I hope we can take it to MIL's house and maybe to the beach. Yes I know these are not recommended until baby is older, but I wanted to spend that COVID stimulus money on something special.

I also bought some PJs from the Gap for me. Maternity Nursing Sleep Cami and Maternity Sleep Shorts. It seems like they are taking for.ev.er to arrive though. They haven't even shipped yet and I ordered on 5th of May. Got ~50% off by using two promo codes. Free shipping and free returns. I hope everything fits, I am not a fan of online shopping for stuff I would usually try on. Hoping the tops are a bit supportive, breathable, yet not so tight that they lead to clogged ducts. I realize this is a big ask. 

I got the following email from Gap yesterday, "we are experiencing delays in processing and shipping your order. We're unable to ship your order within the time frame promised." I am sad because Gap lets you order top and bottom separately, which is nice if you are a pear shape. So I went ahead and bought the following from Kohl's.

Women's Croft & Barrow Lush Luxe Tank & Shorts Pajama Set

These I like the most. The shorts are long enough.

Women's Simply Vera Vera Wang Sleep Tank and Boxer Shorts Pajama Set

These I only like the top. The bottoms are more like underwear than shorts.

Women's Apt. 9 Solid Cami & Shorts Pajama Set

These I hate. The fabric feels cheap and the shorts are also like underwear.

I was hoping to get something comfortable to wear around the house all day all summer long. I hate online shopping, for this reason. Do I return or exchange the stuff I don't like? What would happen to the clothes that get returned? Will they be burned or resold?
