Yo baby is easiest to find, but I also was able to find a plain yogurt that was full fat. I think it was Dannon, but I could only find it in a big container. I'd add stuff to it and Tyler would be fine with it, then the yogurt's taste started to change a few days after it had been opened. It wasn't bad or expired, it just started to taste different and he didn't like it. Irritating, because it was soooo much less expensive than Yo Baby, but oh well.
