1 oz an hour okay?

My milk supply dropped recently (found out my dad has cancer) and with deer season I was not able to pump regularly.

My supply tanked down to less than 1 oz an hour.

Now after pumping regularly I am up to 1 oz and hour. Is that an okay about for a 9 month old?

I am very frustrated and trying to not get stressed about it, but I think my baby takes 1.5 ozs every hour and I am not ready to quit...
