Can I let my 1yo eat butter cookies?

you can as a taste test. But it's too hard for them Break it into smaller pieces for them to chew on

Yes you can if you don't mind. No harm letting them taste. It's more of a personal choice.

Do look out for any choking signs. As it's quite drying. Do rmbr to offer water too.

Go ahead! I'm sure you bub would love it.

Butter cookies are my kids favourite
