Re: Looking for suggestions on building a power...
Version one looks like a Ego Based Entangle with Trigger (insulting the woman), Focus (bundle of cloth), Gradual Effect (to represent it getting increasingly powerful), and Linked to [mental?] Images (for the Baby that isn't there)
Version 2 is, as you say Density Increase (doesn't improve STR / BODY) Usable as Attack, Gradual Effect, Trigger, Focus
Version 3 looks pretty much like the same as the others except they can set the baby down.
