It has the exact same meaning as らしい. The usage difference is a bit lost on me personally but here's what Weblio says: 意味は「らしい」と同じで、特に体言にかかる。

It's based on what is perceived as easier to say and sometimes there are even regional differences. I am not even going to guess what Japanese consider is the correct reading, but my vote is with ねこがた as well.

つつむ has several definitions so that would be the most common reading and くるむ has exactly one: 布・紙などでおおって，中に入れる。A Google image search of くるむ gives a few hints and a Google search of 赤ちゃんをくるむ should nail down at least one common usage.
