Female led relationships discussion

So as many of you know, @Thatguyontheinternet and I just got married in December, so naturally there has been talk of starting a family. For those of you that are new here, to save you from digging through my thread history, I will give a brief outline of our relationship. I have always been naturally submissive, so when I met Thatguy, we explored it more since I had been in a vanilla relationship for over a decade. Thatguy started with little things during our bedroom time and then told me that he has always been Dominant. I was thrilled! I couldn’t have him spank me hard enough! About 8 months into our relationship, we were browsing our local adult toy store when we came across a chastity device and bought it just for fun. I liked it so much, we kept on with it. It has taken me a better part of 2 years to develop my Dominance into something fun for us both, but sometimes still, Thatguy gets restless in his cage and onery since I am the one enforcing Chastity - this is where he differs from most locked men here since he is not naturally inclined to be submissive nor just enjoy the cage itself. But without the cage, the Dominance I have developed wouldn’t work. We have talked and discovered that for him to be submissive to me, the cage is an absolute must. So this is where my question comes in: Since I am more naturally inclined to be submissive and he is more naturally Dominant, when we decide to have a baby, will I default back to being submissive? Will it be the same post-partum? The problem for him is that in order for him to not want to give up the cage and chastity altogether, I do need to keep things interesting between us sexually, which generally I don’t mind, but it sometimes requires extra effort on my part. If he gets too bored he’s more apt to start thinking about giving Chastity up. So I know his concern has to do mostly with the day-to-day realities of having a baby around. If there’s not time for play, he’s not going to be interested in wearing a cage. My concern is that with motherhood, it will reduce my ability to put in that effort. I really like having him caged and all that goes with it so I’d really like to keep it going. I also know that I can’t expect him to spend a year just in the cage before things return normal for us. He was very patient during our wedding planning, since I was in “mushy mode” and stressed with the planning, so I know the second I become pregnant, he won’t instantly ask to be unlocked.
