@path2knb I think so. I went by what the product recommendation was (3 months). I think cause its heavier it might weigh them down. Its definitely worth it though.
For now you could look into the nested bean swaddle. It's a weighted swaddle. We got the sleep sack version (theres a swaddle and a sack) when my son outgrew his Merlin and hes a year and still using it.
And the one for the sack
