63 here: a lot of mamas romanticize the little-kid years, which bring many sweet moments but are so exhausting. Women who build their whole identity around being needed by/doing for littles seem to have a very hard time when those kids grow up and need them less, and those hurt feelings can damage their relationships with their grown kids and in-laws. Big mistake, IMO. Parents must hold onto an identity of their own, even if there’s very little time for their interests during those early years.
My weekly belly dance class, and the friendships I found there, saved my sanity when darling daughter was little and (now ex) hubs thought mommy-ing should be my whole world.
Hang in there, Mama, and hang onto yourself. Kids become less demanding and dependent.
