How your baby sleep through all the night ?

ANA • Mom of 2💙 💝

Hi. I’m a EBF mom and my baby girl is 5 months. I see other lucky mommy saying their baby sleep 12 hours in a row. What do you ladies do about that? My baby wants do eat at least every 2 hours day and night. I’m so exhausted that I’m sleeping with her now cause it’s too much to get up so often every single night. I have another kid 3 years old so imagine how hard it is. ( and we just put him to his room , he slept with us for the last six months ). Any tips???
