: 2 small kids at home will kill of many women's sex drive. You can try doing more to help with the kids, taking both of them so she has time to herself, taking her out on date nights to remind her she is a woman and wife and not just a mom. But often with 2 or more babies the mom simply cannot get her mind off the kids enough to relax and want to share herself with her husband. You may be married to one of those moms.
Try the above ideas. If they don't work, you will have to be patient unless you are willing to divorce over this. How you handle not getting any sex probably won't affect how much sex you get now (close to zero no matter what you do), but can have a huge impact on how much sex you get when the kids get older. If you are a whiny jerk now, she won't be much in the mood for sex even after she stops breastfeeding, the kids stop clawing at her all day, they can potty nd dress and feed themselves so she isn't doing so much physical work to care for them, etc. Might not be anything you can do to get more sex now, but there is alot you can do to ensure you won't be getting any sex later, either.
Oh, and if she is the type of mom who can't turn off mom mode and get back into sexy mode, you might want to wait a few years to have another kid. The second small one isn't twice as much work, it is infinitely harder. With one in diapers, when they nap you can nap or do housework. With 2 small kids, when one naps the other is likely awake and wanting mommy time. There is no respite. It is a relentless demand from the kids for time and attention. When Dad asks for sex, that is just one more chore on top of the unending pile of tasks.
I know my post is not very optimistic about your getting lots of sex anytime soon. But at least it gives you an idea what you are dealing with and why, from her side, it always seems she is too exhausted and stressed to have sex.
