Sleeping through the night?

Kayla

My son will be 9 months old on the 6th and he doesn’t sleep through the night. He never has. He wakes up every 4 hours on the dot to eat and he pees though his clothes every night as well. I change him as soon as I lay him down for bed. Is this normal to not sleep through the night? Is there anything I can do? I need sleep and I’m just not getting it. We sleep in the same room bc we don’t have a big enough house just yet but he’s in his own bed.
