Don’t most (if not all) churches have a “cry room” where people with small children can go so the if the children make noise, it won’t disturb everyone else (but they can still view / participate in mass)? Perhaps until the child is old enough to not be feed during mass, the parents can use the cry room???
Just a suggestion.
Cry rooms are hideous (and not every church has them, Thank God). They are all the way at the back of the Church in most cases–you can’t see anything. Separated from the rest of the congregation by glass–I always felt like I was watching Mass on TV. Bad sound. Badly behaved children and parents…Bad all around. Best to avoid the cry room, unless absolutely necessary.
It’s best to teach children to sit in the main area of the Church. The ages from about 12 months to about 36 months can be tough, but very doable. If puffy cereal is needed and can be done neatly, I don’t see a problem. We did this when our first child was little. As we added children, however, food, toys, drinks, books, etc, became more of a hinderance than a help. We banned all these things at some point and never looked back. However, in some circumstances, dry cereal can help…fed one at a time to the child and not in a crinkly bag or loud container

I also recommend sitting up front so the toddler can see what’s happening–action is always a good thing. If the toddler is getting too noisy, walk back the vestibule with them and hold them until they can be calm again and then try going in again. Repeat as needed. It’s a process and it won’t happen overnight.
As a former convert, I know it can be scary sitting up front

Try to get as close as you feel comfy.
To those who have a problem with offering dry cereal, I’ll ask: which is worse-- a crying, super wiggly toddler, a distracted quiet toddler fed a bit of cereal, or parents who don’t attend Mass (or won’t convert) because some parishioner gave them the hairy eyeball for daring to keep their child quiet using dry cereal? I know I’ll take a bit of dry cereal and a Mass attending families
