6hr without eating

Kat

My baby is 4 weeks. Doctor told me weeks ago to not let her go over 4 hr without eating but that was before she went back to birth weight. Now that she’s gaining is it ok she went 6hr? I offered at 3 hR mark and she wasn’t having it. We’re breast feeding for the most part. I pumped and she drank 2oz after 6 hr
