hi mummy, one month old babies do not sleep through the night because they have not reached a sufficient body weight to sustain them to fast at night. baby’s stomach is small, which makes them cry for milk every few hours. babies only sleep through the night many months later unfortunately, please mentally change yourself for it. in the coming months there are also things like sleep regression every few months, which throws your sleep routine out the window. do prepare yourself mentally and manage your expectations on baby’s needs.. i’m surprised nobody told you there will be a serious lack of sleep for the first year!
best to have more realistic expectations, newborns do not sleep through the night. my baby slept through the night at 4 months old, whereas my friend’s baby still never sleep through the night at 8 months old, waking up every few hours for milk.
