How long have you taken off work?! Do you feel guilty for going back??

Ashley • I'm married to an amazing man, I have 2 little boys from a previous marriage. Thought I was done having children but my husband and I want another one so I joined this group!
I have 3 children. A 9, 6, and now 8 wk old. I was a stay-at-home mom for the first two, only working part-time, about 12 hrs a week, but when my youngest son turned 3 I was promoted to a new position and started to work full-time. My little girl just turned 8 wks and I was supposed to go back today and called off..I'm really struggling to go back but we truly can't afford for me not to...Anyone else going thru this guilt?!
