Hi all, my son will be 4 months old in a week. This week he’s had some congestion, no fever, appears to be teething (drooling, fussy, chewing everything, and I can see what looks like the start of teeth in front bottom gums), and has now stopped sleeping through the night. He’s sleeping more today as well. He is still able to be happy and play at times, but his naps and feeding are all over the place. I’m a FTM, so I don’t know what to expect with teething. Unsure if he’s sick, teething, or if he happens to be experiencing sleep regression. Anyone experience anything similar?
