Poop picture - Milk protein allergy? TMI

Brooke • Stage 4 endometriosis // TTC 18 months // Laparoscopy August 2018 // BFP January 10th 2019 // Jocelyn Brielle born Sept. 10th 2019 💝 // TTC 1 month // Baby #2 due May 28th ‘21

She’s on Similac Pro-Sensitive and also the Soothe drops from Gerber. Still fussy and seems to be uncomfortable throughout the day. Does this look like a milk allergy? We have her pediatricians appointment on Tuesday afternoon but would like to hear others experiences.
