19 week old short naps

Nikole
My baaby is 4.5. When sleeps 830 to 6 or 7 am. She takes very short naps at 30 to a hour long with a hour and a half between if that. And takes about 5 naps a day. How do I make her sleep longer without her freaking out tired by keeping her up? I want her to sleep early long naps. What is working for you all?
