Poop?

Malorie • Owen's mommy 2/6/19💙 Lillian's mommy 9/5/20💗

So my son is 11 months now. I still breastfeed like all the time as well as baby food. Yesterday my sons poop went from regular brown mush to light yellow watery liquid. He pooped 4 times yesterday like that. Has anyone else experienced this? He already has a doctors appointment set up.
