Hi K.,
OK, I think I can help in this area.
Plan A:
Go buy a bottle of wine,(you must have this on hand as a back up at all times) Then you tell yourself that when your husband comes home, you are going to flirt and imply that you want to have some "special" time with him at 8:02pm that night.(verbally say this but also give a lot of body language) Flirt,tease and flirt and tease some more. Make his favorite meal also and at 7:00 have a glass of wine, after the kids are in bed,go take a shower together then initiate SEX! This part is very important...you have to do the initiating.Have fun!!
The next day you have to call your husband at work and say he was amazing and tell him that "He's It"! (as in a game of tag)-so it's his turn to initiate and plan.
Plan B:
Call me...I can babysit! ###-###-#### My kids are older and I would welcome some babies. Get a good support group and get as many as possible so if someone says no, you call the next person. Make a copy of this list and make sure your husband has a copy of it too so he can plan something secretive if he wants to surprise you!
Good Luck!
