We have issues getting our PetCo baby to eat anything non mobile as well....and he is so small opening his mouth for meds is horrible even with many tricks...
What I've resorted to as all meds seem to instantly kill the crickeys, we put it literally on the back of supwrworms. I can see if it flings off easily, and he doesn't waste any time gobbling those down lol.
I occasionally will have to still do the meds by mouth and have used an extremely thin card to pry his mouth, as well as slightly pulling on his chin area but just ever so slightly.
So happy your babe is ok!!! Scary scary stuff. Good work getting her right in, it's what we must do when the few stressful times occur.
