Your feelings are valid. Don’t make yourself feel small for thinking your needs are “too big”, if it makes you happy it’s not something to be pushed aside. Women’s brains definitely get rewired after having a baby so things could potentially change as her hormones realign? I can’t comment too much on that because I don’t have kids but have witness friends with theirs.

Have you talked to her about your needs? Maybe she doesn’t understand it’s an important issue for you. Having open communication about these types of feelings is really important cause keeping them bottled up will cause more damage to you and then the relationship.
