Hi I was a very hands-on stay-at-home mother to my 4-year-old son till last year. I quit my full-time work when he was born and I was doing only freelance and part-time work. Now that I have joined full time work, I feel so guilty to leave him at a day care. No issues in the day care, but I just want to be there for my son when he comes from school. At the same time, I don't want to have a huge career gap or lose this great opportunity to work. How to overcome this guilt?
