I don't think Carys would want baby nr 2 to wear the same clothes as Amber. She'd want a whole new wardrobe!
Also it makes me sad that she never gets any second hand clothes for Amber, it's so much better for the environment and secondhand baby clothes are usually in really good condition as they hardly wear it. My girls wear second hand most of the time, we got twins and my husband lost his job due to the lockdowns, I only buy some clothes for them that I really like. If I had more money I would do the same, I love reusing stuff. It makes me sick that Carys buys Amber (or gets gifted) seriously like 20 different Christmas outfits.
