I would think if the baby food had probiotics added, it should certainly be listed on the jar. I'm certain there are many baby foods out there that are nothing but fruit or veggies.
For getting meds down, I can *usually* fool mine with fresh mashed banana. I make up my own meds by crushing the pill and mixing the powder into strawberry syrup (calcium free - they add calcium to everything these days). When they catch on (like this week with Munster), I have to get creative. I found two things that really seem to get them to eat their meds are the fresh banana mixed with lemon wafers (
this is what I use), or this week with Munster I used vegan chocolate ice cream sandwiches (mainly, the chocolate wafer part). I added a pinch of salt to it and a pinch of nut butter, even a pinch of a calcium free vegan ice cream if needed, and he's eaten most of his meds down. There are quite a few vegan ice creams that are calcium free, thank goodness, as that's usually part of my back up plan for meds.
For feeding a sick rat, I noticed with Munster this week part of the issue seemed to be that he would lose focus when he was at his sickest. He would take a bite, look away, and right when I'd think he was turning it down, I realized that if I dipped my finger in it and put it up to his mouth, he'd eager eat more. It was as if he just got distracted. Now that he's better, I don't see that at all, but when I try to feed him I always make sure to offer it multiple times, usually starting with off my finger first. I also multiple types of food in front of him so hopefully he'll quickly find something he'll like, and then at least I know quickly that he still has an interest in food.
Another thing to keep in mind (I almost forgot this week) is to have a water bottle on every level. Once I did that, I noticed Munster drinking more. It helps ensure that they aren't lacking water simply because they may not have the strength to get to the bottle. I also gave Munster *a lot* of strawberry ensure and coconut water this week, the main thing he truly enjoyed when he was sick. I sucked it up in a syringe and slowly dropped it out for him as he licked it down.
Hang in there love. You are doing the very best you know how for them both. I know it begins to feel terrible when you suspect that the only things they are now associating you with are the bad things, but I do think they let it go faster than you think. I spent my first real week with Munster taking him right in for surgery, home for recovery, trying to force foods into him, giving him shots, etc, and he still wants nothing but love from me. Even at his sickest, he just wanted love. Just love them at every possibly moment you can. Talk to them, pet them, give them little rattie grooms with your nails. I think somewhere deep down they understand that we don't really intend them any harm.
