I am very picky about my babies treats as well, because a lot seem to bother them.
I buy Yorkie Yummies from chattiesmom and they don't bother them at all and the LOVE them.
I also use baby carrots a lot, I swear my one baby would pick a carrot over a steak any day
I also use the gerber graduates, they are easy to travel with and the kiddos love them.
Basically I just stick with REAL food or those treats made by YT members and I have been safe and the babies remain happy.
