I always feel guilty for leaving my kids behind but i have to work. Any tips to help me feel less guilty?

Isn't your answer in your question? "... I have to work." If you're feeling guilty, probably you don't really have to work but want to work, in which case, you eed to ask yourself why you want to work: self fulfilment, etc?. Working mum here, & i know i will feel a lot more miserable when I'm home full time. Just my personal preference. I don't want to trigger another classic mum at work vs home war
