Napping help please...

Sarah

FTM here...My daughter was a great napper until she had her 6 month shots on May 21st. Now she will only nap on me, if I put her anywhere else she cries to the point of throwing up. And I won’t let her do that. She’s super stuck to me as well, even cries when Daddy holds her. She has no problem going to bed in her crib but naps she refuses. Advice needed please!
