How can I fix this ??

L • Dec2019 💗 August2021 💙

Anyone else’s baby sleeping great during the day and is a little brat at night ?? She usually sleeps from 9 or 10 am to 1 then stays up until 3 sleeps from 3-5 or even 7 sometimes I try her routine at 8:30 however she’s always up until 11 pm or sometimes even 1 just wanting to eat 😭 she has her days we’re she’s amazing and will only get up twice at night but the last couple days she keeps me up allll night. Am I letting her sleep to much during the day ?? How can I fix this so she knows nights are for sleeping too . She’s currently 6 weeks today
