bluelily,
Just came in n saw the bit abt your jr. My baby girl also like that at one time. She poo n poo but still active. I suspect teething but no sign of teething. Couple of days later, she developed some rash. Went to see dr at TMC. He said its probably virus infection but recovering stage, so no need for medication.
Dun tink its the avocado. I gave my girl avocado n no problem wz poo, even tho some say avocado got laxative effect.
Anyway, hope jr gets well soon.
