Naps and bedtime

Our first nap Lo is willing to sleep in her crib. She's also half awake and sleeps from 30-45min she uses her thumb to go back to bed. Second nap, I usually have to be beside her for her to take a longer nap 1-2 hrs. Then bedtime she's glued on to me so we co-sleep. Wakes up every hour complaining sometimes its congestion, gas, reflux. It has been like this from 5 months. 2-4 months she was doing so well in her own bed. Is this normal? Can't understand why her nap can fall asleep easier but not at night!!!
