I must be weird. I don't have "in the house" and "out the house" clothes and i sleep naked or nearly naked so there's no "staying in PJ's" option either. That said i don't "dress up" either. Jeans and a top (nursing top always right now) is my usual fare. I have 30-35lbs to lose from my getting-less-recent-all-the-time pregnancy too!
So generally DP walks in to me cooking, and the kids excited to see him (DD1 screaming his name, DD2 smiling and waving her arms to be picked up). He usually comes to find me, i give him a good squeeze and a kiss and ask him how his day was and he briefly asks me how the kids have been. Then he goes to get changed, usually accompanied by DD1, sometimes he takes the baby too and lays her on the bed to chat with himself and DD1 while he's getting into jeans and a tee himself. While he's getting changed i am finishing and serving dinner. We all sit down together to eat every night. Over dinner we talk more about our respective days and the food and plans for the weekend etc..
After dinner he clears the table and makes tea while i nurse the baby, then we drink tea, he snoozes a bit. Then one or both of us does bedtime (bath/shower, teeth, stories for DD1) and i usually lay with DD2 to get her to sleep on our bed.
Every night, before we sleep, we watch a dvd together (usually something from tv, serialised, like family guy or similar) and chat.
Really, we're in love for more than one anothers looks. I like it when he dresses up. he likes it when i wear a bit of eye-liner. But neither of us expects it every day of our relationship or anything.
