My LO has been extra clingy in the day, takes short naps (30-40mins, or less sometimes), and has been having difficulty++ sleeping at night. Once I put him down for bed, he will wake up within 30 mins crying hysterically and it takes a long time (ytd took 1.5 hours) to soothe him back to sleep. The night wakes and crying will continue multiple times through the night. He is 6.5 months now.
Other than teething, are there any other reasons for this drastic change in his behavior? He has been like this for a week ?
