DS 7m, MIL looks after him for a few hours once or twice a week while I MN study. Do I just suck it up as she is being so helpful (not that she minds - she loves having him) or, since everything he and we eat is cooked from scratch, ask her not to use jars, which is how she cooks. Am I being undgrateful/ unreasonable/neurotic? I am more than prepared to stock up her freezer with stuff I've made, not sure how she'd feel about that tho.
