Toddler sleeping for 3-4 hours while at her dads?
A mother and child's bond is so strong, she probably misses you. Maybe get her a soft teddy bear (or something similar) with a velcro pocket, record your voice singing and talking tell her good night, etc., then put your recorder inside the bear. Tell her dad she can sleep with it and show her how to turn the voice back on. It will almost be like you're there with her in a way. See if it helps. Good luck!
