I personally don't agree with putting clothes on children to sleep in. Pajamas/nightwear exists for a reason. I think you should be getting up earlier if that's what you have to do.
Personally, what I would like the most is your husband to agree with you and not judge you - you are doing your best and especially with twins ! I think it is absolutely fine! Especially if it saves you from the frustration. You could do the clothes in the morning if it isn’t too too much (not that I have any problem - I grew up in a household where we didn’t have separate sleep clothes - as long as they were clean we could sleep in them, they didn’t have to be nightwear)
I think you are doing the right thing and I appreciate you man you are working and doing all this with the twins 🙌 do whatever makes your life easier to be honest
Before I had kids, yes, I used to think this was absurd. How I have children and have to juggle the getting ready and tantrums etc, not at all. Whatever works for you and makes life easier.
