I picked 4, but I just woke up and didn’t see the option for other. After some trial and error with our older kids, I decided to cut toys out altogether. I have made a few exceptions due to raging tantrums, but 99% of the time we don’t bring toys or books with us.
As for food, my general rule of thumb is to cut it out after age two. Prior to that, we had a spill-resistant plastic container we would fill with Cheerios. I would monitor it closely and clean up anything that spilled. However, we go to the early Mass on Sundays. Sometimes we’re in a real hurry in the morning and don’t have time to feed our youngest anything before we leave. On those mornings I’ll sometimes grab her something as we leave and let her bring it in if she doesn’t finish it in the car. Going 40 minutes without food may not seem like a big deal to an adult, but it can be a major issue for a three year old who hasn’t eaten since dinner the night before.
I will point out that our inhumanely strict rules about food and toys have been challenged repeatedly over the years. We have a nephew who’s rapidly approaching his teen years. On the rare occasions that he’s taken to Mass, he still gets to bring his “church bag” which now includes his smart phone, tablet, snacks, a drink, some toys at a book or two. That influence has led to grandparents (who absolutely, positively know better) insisting on bringing candy and chips for the other grandchildren as well. I caught all sorts of heck a couple years ago when the goodies were being handed out before Mass and I refused to let our kids have them.
