Hi J.,
Have you looked into a nanny? We are not only both working, but both in the Navy (can have long hours, underways, overnight work, etc.) When we lived in Italy, my sister came to stay with us to help with my then 4 yr old. Having the consistancy of the rules and the environment helped tremedously. She is now a mother as well as a mother's helper where she can bring her own son. It was a win win for both of us. Since we were family and she was 18 it was free room and board in Italy in exchange for home and child care. Very good economics for us!
My friend who has twin 3 yr olds also uses a nanny, (her 19 yr old niece) and now that she is going through a divorce the niece/nanny has been even more of a God send. She does recieve a paycheck, but it was still cheaper and more convienent than daycare do to the hours and deployments this mom had to work into her schedule.
P.S. The niece/nanny also had nothing to do with the divorce!
Good luck with your decisions and the bonding that will come or your love, care and concern for your son!!!
