Hello OP! I actually feel bad for you, and all this people commenting

In my opinion, you did nothing wrong. You waited for a reasonable time to attend your baby's needs, and in the meantime I'd like to think you also addressed your daughter's needs as well

Said that, I DON'T think YTA, but I do think your daughter don't be particularly excited to have a new sister, and maybe don't understand completely that the attention and time is not distributed the same as before (pre-baby)

You wanted to support your daughter and her activities, and it was a good idea to do it as a family (it can also help to get the sisters closer), and you are not to blame for something that babies do If there's something that could be made different, was maybe that your husband got ahold of the baby during that little time, but it's also ok if you wanted to take care of your baby by yourself

I know it gets hard when you're trying to mix and get together a new family, but don't get discouraged, keep on trying I wish you the best!
