Yesss. I was thinking lower iron too.
I’ve joked my baby can’t have anything nice or “good” for him because he’s been left unattended (I’m cooking in the kitchen w my back turned a little too long.. lol) with his books and decides he wants to eat those.. I haven’t had him try anything else but I’ve also thought this is just something babies do, I’m hoping he’ll just grow out of that?? I’m not much help but in the same boat!
Mine does! Paper towel too lol I think it’s lower iron. I haven’t tried seaweed. I think it’s just something they like and are going to try to do no matter how much we tell them no
