These pajamas are adorable and good quality. They fit perfectly once on the muse. They are very hard to get on the little mouse and I could do it ok but it is impossible for my 4 year old who owns the mouse to take them off or put them on. My suggestion is either don’t buy pajamas or by them and put them on the mouse with the intention of not removing them because doing it every morning and night has bot been a great experience for me. I would love to see this same pair with Velcro for the kids to be able to do it.
