Re: poo poo in the midnight
My baby Hayes also was the same as your son, when he was under 6 months old. I was extremely tired to change diaper during midnight, a very cold night.
You may try semi-solid foods for baby, poo poo condition gradually would be improved. Meanwhile, you may look which foods you took that trigger baby from sensitivity.

Hayes had been breastfeeding for almost 3 years, then naturally weaned by himself!
Wish Hayes with Love, Peace & Joy!!
