Naps & feeding!

Okay so I’ve got a sleep/feeding question!

So my baby is 5 months old and eats 5-6 oz of formula every 3 hrs.

I usually put her down to nap every 1.5-2 hours. She would sleep for 1 to to 1 and 1/2 hrs then we’d wake her to eat (besides at night).

Lately her naps have been super short! Like 40 minutes. So I’m thinking I should lengthen her wake window to maybe 2.5 hours?

But then how is that going to work with feedings if she eats every 3 hrs? She usually eats right after waking.

So if she eats after waking, I’ll put her down 2.5 hours later and then she’s “supposed” to eat at the 3 hr mark which would be 30 minutes later. But she needs naps longer than 30 minutes!

Will she just keep sleeping and wake when she’s hungry, even if it’s longer than 3 hours since her last feeding?

So how does that work? Any advice/input? 😂
