My 7 month old will wake up in the middle of the night screaming. He acts like he is having night terrors, or something is hurting him. Is he to young for night terrors?

I really have no idea about the night terrors, but you could always look in to whether something is actually hurting him. My son was about that age when he got pin worms. They're active at night and can cause extreme itching around the anus. My son would wake up screaming and need to be held and consoled back to sleep. It took us awhile to get to the root of the problem and get him on antibiotics which helped him overnight! You really can't see them, so it took my son actually getting a yeast infection from all the scratching to realize what the issue was. Good luck and I hope your lo gets some sleep soon!

teething can start anytime between 4 months (or earlier in some kids) and forever, so it could be teeth related.... laying down makes teething pain much worse for little ones!

could also be gas.....

i highly doubt nightmares could be the culprit at that age....
