Is it safe if i mix enfamil A+ ready to feed with milk while i go to the dentist.

My baby will not take formula and i do not respond to pump very well at all ( i can only pump two ounces) i can still get milk out with my hand. Are there any tricks to help me respond better?

It was a last minute get in to the dentist so i was not able to prepare for a few days.

(Wisdom teeth aren’t coming out and i don’t have room for them plus i have an infection where they are coming, that’s why it’s so last minute. We were busy with appointments and immunizations today.

Update baby won’t take it even if I do two ounces of my milk and on of enfamil😬😬

He eats every hour,
