Would you listen to the Dr?

Hi everyone! So for reference I’m 5 ft and 115 lbs, my husband is 5’ 4” and 170 lbs. We just had a baby boy who was born at 5 lbs 8 oz, so a lil guy. He was sleeping through the night but at his 2 month follow up they told me to wake him up to eat even though he was 8 lbs and 5 oz (still small but growing). They said he’s in the <1%… but like.. he was a small baby and he’s gaining consistent weight. We had a follow up and of course he was still gaining weight and they told me it was cause of the midnight feedings but I feel like it’s just him gaining weight and growing. Idk.. My question is should I listen to my sons hunger cues and not wake him or should I listen to the Dr?

Also I just want to say I DONT have an issue waking and feeding him I’m just curious if anyone else has experienced this and if they followed their “gut” or went with the Dr.
