My 7 month old boy has always slept well during the night. Recently though he's started waking up crying 2-3 times uncontrollably. He appears to still be half asleep though, eyes shut, and is a dead weight when I lift him. Someone suggested to me it might be related to teething. Anyone experienced this? He's had his hands in his mouth a bit more than usual recently but nothing major. Contemplating giving him teething granules but don't know if I'll be wasting my time.
