Timothy indicated he’s hungry but when I gave him the boob, he dropped it after a few sucking motions and started to cry. I tried giving him the other boob (sometimes he shows preference to one over the other), I tried playing with him, shooshing him… he cried and cried and cried. Honestly, this was breaking my heart. After 30 minutes of crying at the top of his lungs, I tried to put him for a nap. He started sucking the soother and more crying ensued.
And I was about to leave him with my mil to go see the dentist.
He was obviously hungry but couldn’t eat; he was obviously tired but couldn’t sleep.
He was obviously teething.
Thankfully, I had a sample of teething drops which I gave him. Five minutes later he stopped crying and smiled hesitantly at me.
I waited a bit and gave him the boob. He fell asleep eating.
I left him with my mil and instructions re: teething drops. My heart is breaking.
No wonder he started waking up in the middle of the night, after sleeping thru the night for the past 4 months. Poor Timothy 
I’ve heard amazing thing about teething drops or tabs. I’m glad he was able to get some relief!
