Sleep training question

So I started sleep training my daughter and tonight will be night 3. Both nights have been rough so far... crying immediately when put in the crib. But my question is if you sleep trained what did you do for naps? I currently hold her for all of her naps but I’m wondering if it is confusing her too much for night time? But then again I want her to get some decent sleep during the day... what should I do?!
