Completely normal! Are you nursing or bottle feeding? Feed the baby right before bed. If you are nursing, have someone else (if possible) get up with baby and rock him back to sleep. If that doesn't work then nurse him.
My 19 month old only VERY recently started sleeping through the night. And if he gets sick or has a growth spurt he will be up to nurse during the night. Perfectly normal.
You can encourage sleeping all night, and take steps to help the baby learn to - but remember it isn't going to be permanent. You may have days baby sleeps all night, but then he will be back to waking up again. Just keep working on it and encouraging it. My 2 1/2 year old still gets up once in a while in the night.
:D Sorry. Just get used to being exhausted. You have at least a few more years to go. :D
