10-month old sleep regression?

Our (almost) 10 month old has been difficult at bedtime recently. He has always been a good sleeper-when he was first born, we even had to wake him to feed him. He has slept through the night for as long as I can remember. We have always put him to bed when sleepy and not had issues. Recently, though, he has been screaming at bedtime, not settling down, getting so worked up and upset. He has been waking up at 3,4, or 5 in the morning (unusual for him) at times, too. Sometimes I think it is teething (baby Orajel had even a godsend!). Other times, it is almost like he just doesn’t want to miss out on what we are doing. I know he is tired-sometimes all we do is just hold him for a few minutes, or put him in our bed, and he crashes almost immediately. For anyone else who has experienced this-what is your secret?! What has worked for you?! Thank you!!
