trying to exclusively breastfeed

Ella

she has the 6-8 wet diapers and about 3 stools per day BUT they're not very wet nor very much poo, as compared to when she was getting formula too...is this normal/okay or a sign she's not getting enough milk ??? my babe is 7 weeks and has always had some formula bc I didn't think I made enough milk..I can pump for 20 mins and only get two ounces combined, two hours later only an ounce combined. I don't pump anymore and feed on demand. anyways she's been very colicky, ped keeps switching her formula.. so I'm trying to just breastfeed to see if it helps.
