Help! Anyone rocking their infant to EAT??

Hi all!

My baby is almost 3 month old and still uses the avent 1 nipple. He gets upset when he eats and I have to rock him to eat more and more often... specially if he went full on crying cuz he is hungry.

We have tried to feed him with the 2 because I thought that would help but he chokes with it pretty easily.

I thought maybe it was reflux but he spits off very little and doesn’t throw up almost ever. Also this is only during the day, at night he eats full bottles of 5fl oz no problem.

Anyone has any idea of what to do? Is anyone out there also rocking their baby to eat?? I’m just so tired...

Thanks y’all!
