Baby won’t stay asleep during the day

Hi Mamas,

I have a 6 week old who has figured out night time sleep. She’ll sleep for 3-4 hr stretches at night, but won’t stay asleep longer than 15-20 mins during the day.

I’ve literally tried everything! I even replicate the nighttime environment/routine and nothing works. I’ve bought different swaddles, pacifiers, etc and still the same result.

Do we think this is just a phase or am I doing something wrong? I’m so tired and I’m at the point where it’s starting to break me down.
