Hi, just a quick question. My boy is 5 months old and I can feel a bump on his bottom gum and he is constantly chewing hard on everything so I'm pretty sure he's teething. Does teething affect babies sleep? I'm trying to figure out why he is sleeping so terribly (frequent wakings, tossing and turning in his cot for hours, whimpering occasionally and sometimes waking for 2 hours at night) and wondering if it has something to do with teething. Any thoughts from those who have gone through it?
