I can relate to your experience. I am a SAHM at the moment, but when my DD was 13 months old I returned to work. My DH only had casual work at that time, so he resigned and became the stay at home parent.

I missed her so much. I just wanted to be with her. I felt like I was missing out on all the little, mundane things that she and DH shared during the day. DH started taking her to the playgroups that I used to take her to. He was seeing my friends more than I was. I really wanted to quit work, but DH didn't have a job. I felt trapped in my job. My heart wanted to be with her. I felt so sad about it.

Then, my DH was offered full-time work out of the blue. So, I became the sahm again when DD was 21 months old.

My DH recently commented that he wouldn't mind being SAHD again when DS2 is weaned. I don't know how i feel about it though. DS2 is a long way from being weaned so I don't have to worry about it yet.

In hindsight, I am actually glad that DH had a time at home with DD. It means that he has more understanding of what it is like for me at home. He also had a special time with DD that most father's don't get to experience.

I really feel for you though. It is so hard to reconcile it all. You miss your son. Are you able to have special one-on-one time with him on weekends?
