Unfortunately not much you can do, with baby being so new they haven't yet got their sleeping pattern sorted.. In the next few weeks it should start to regulate.. But they usually do it by themselves xx

my little one is the same. x

they do eventually start staying awake more during the day.

my little bubba slept most the day first few weeks.

like what jayden19 says try keeping her awake more during the day.

I know it's hard but it does get better try and be patient.

my girl slept 4 hours at a time during the day and every 2 hours a night.

now she wakes up once in evening sleeps all night.

She's 8 weeks old.

Hugs. xxx

Bless you must be exhausting maybe try and keep her up a little more in the day talking and and singing??? It's a difficult one hope you sleep soon x
