Sleeping Trouble!

Stick with me.. this will be kind of long. My son turned 2 this month (December) for the last 6 or so months he’s had trouble going to sleep and staying asleep. He’s got a (twin) sister, and older brother who have no sleeping trouble.

He fights bedtime for sometimes over an hour! About an hour or two after he finally goes to sleep he will wake up screaming, and crying. Nothing will calm him, cuddles, songs, snacks, drinks, toy nothing works.. and it’s pretty consistent every night that this happens.

Is this normal? I’ve never had to deal with sleep troubles. I brought it up to the pediatrician, and he seems to think it’s typical toddler behavior. (He’s a great doctor and great advocate for our kids. He’s always willing to push for answers.. ) is this something that we should just try to “redirect” or should I push for more answers?
