LO sleep vs. eat

I'm so annoyed, mainly at myself and I need to vent. Over the last several weeks I've been feeding my 6 week old every 2-3 hours during the day. He only gets 2oz formula at a time and can't handle much more. I wake him up if he doesn't wake up on his own. It's been working well. He even slept 5 hour stretches a few times at night.

Then a friend came over, held my LO while he slept. He had been asleep longer than I wanted so I went to wake him; she held him and he slept for 5 hours. She says, no don't wake him up. Never wake a sleeping baby and gave me this look. Then proceeded to tell me how she never woke her son up but to "do what I want". I felt guilty and second-guessed myself and what I'd been doing. Then a day later, my mom comes over... Tells me the same thing. Again, LO is asleep.. longer than I want during the day because he's being held. But I listened and didn't wake him up.

Then to top it off, my husband hears these other women/mothers say such and starts repeating it to me. So I think again.. maybe I'm wrong.

Guess who's up and wide awake now?! My LO... Because he's hungry and I let him sleep all freaking day for two days in a row. Should've listened to my gut and what I'd been doing.
