There's no going back I'm afraid - a baby is for life - 20 years - not just for Christmas. Your partner remember is also having to adjust to a new lifestyle, and not only that, seeing you as a different person. Your body has changed - he has to get used to that as well. In fact you are no longer the couple you once were altogether, so the idea of going back to how you were is, I'm afraid, out of the question.
The best you can do is to in fact adjust your currentl lifestyles to accommodate your new baby, and of course for you to try to make yourself appear to your partner as a woman, and not as a mommy. You are a woman with needs and you need to make this clear to him - at the moment he may even be too afraid to come near you, in awe of the whole birth process, in case he hurts you or so on. Reassure him and remind him big time that you are a woman, as well as a mother.
