I think a marriage can grow apart after a child but that does not mean you can't work on getting it back. Honesty between the two is a must. Well at least with my husband and I. Setting time to just talk and share what is on your mind helps. We started having a time right before going to bed to cuddle and be able to share our day, concerns, feelings and to let each other know if we felt we needed more of something. Like some times I need more kisses or more hugs or other things. This has helped cause now we know why one or the other has not done something together. We can't read each others mind and having this time has worked. I hope this may help you if you are not doing it already. There are more things if you would like to know.
