What kind of hour does your husband work? How can you have no time with eachother? I am a SAHM, have a 16 month girl, and I run an In Home Daycare, and still have time with my hubby that works two full time jobs. My suggestion is that you have a set date night. This new baby is going to come, and you are going to need his help. Take even the bath time with your son as a few min to sit and chat. My hubby and I sit beside the tub and we blow bubbles, and play with our daughter. That is a special time between us. My hubby and I go for walks. We usually take outr daughter with us every time we go out, but we still have "US" time when she goes to bed, and nap, ect.....
How does your husband feel? Take showers together. Snuggle, and just lay with eacother.
