Not sure what happened but our LO was sleeping through the night then about 2.5 months ago he started waking up a couple nights a week then it’s like regular nightly and sometimes we’ll be holding him for hours. He won’t go back and stay down in the crib. I’d cave and put him in our bed again but we have our 4 year old in our bed because they have one room. Plus he doesn’t sleep well next to us just in our lap rocking. We’re exhausted and frustrated. I can’t remember my first being so difficult for so long to put back down at night. I held him an hour last night put him down. He slept for 20 min then woke so we left him cry for an hour then my SO held him. Right now he’s not even going to bed. So we’re letting him cry. It just feels awful to me.
