Is it ok to be looking forward to going back to work

I go back to work starting next week. My little one will 2 months old and I have an almost 3 year old and I am kind of happy to get back to work. It will only be part time and I want to start talking to work and get a mental break from it all. I know I’m going to miss them like crazy when I get back but i feel like I’m a better mom when I’m working and I cherish the time more!
