My son is going to be 9 months in 2 weeks .. he just recently has 2 bottom teeth coming in .. the past few weeks he does not sleep through the night like he use to he wakes up crying and yelling for us .. falls back to sleep and then up again 2 hours later .. recently started not taking his bottles like he use to he has 2 ounces here or there but will eat his meals still.. is this from teething ? And will the sleeping get better again😩 we’re so tired lol
