When it comes down to the baby being the one who unfreezes her heart, I thought that too. I wasn’t thinking it’d be a hug though or a kiss, but probably Emma will be holding him and as she completely freezes, he’ll look up at her pained face and shed a single tear and POOF emma unfreezes. A tear of true love.
Or they could just have him do it intentionally. By shooting out some beam of True Love to save his sister. But I don’t like this. If he does so, he’s going to be some super powerful baby who can wield the strongest kind of magic and therefore whenever something happens we’ll be like “oh just have baby snowflake zapp em with some love”. Although, super magic baby worked out well for Charmed.
