is this considered sleeping through the night?

My LO has been doing this for a couple of nights now.. he'll go to sleep and wake up every 3 hours but will drink his bottle when he wakes up and then right after go back to sleep.. around 7-8am this stops and it's more difficult to put him back to sleep or he doesn't want to sleep anymore. So is this considered sleeping through the night? Even if he wakes up every 3 hours for a bottle and then back to sleep? This is the closest we've gotten to sleeping through the night lol.
