Baby resisting sleep

Hi all, my little one completed 5 months today. Since the past 3-4 days she has been taking longer naps in the day and wakes up cranky from the naps. Before she would sleep easily at night now she has been resisting sleep and will only sleep in my lap. If I put her down she starts crying and this goes on till 12.30am till she’s in deep sleep. Wakes up early by 5am. Is this phase? Is it normal
