Sleeping through the night

Victoria • My first baby was born 12.12.17 💙 Roman Anthony

So I’m seeing tonsssss of posts where people say their baby is sleeping through the night, and even some sleeping through the night while in their crib in their own room. I feel like I’m doing something wrong! My baby still wakes up every 2.5 hours at night for a bottle. And he eats RIGHT before bed and is full after and falls asleep. Am i doing something wrong? Is he just waking up out of habit now? How can I help my baby sleep longer and better 😩
