MIL and keeping the baby awake during daytime

Alicia

My MIL came and stayed with us for a week and Every time she had the baby she cried so she would wrap in a wool blanket and take her outside (July and Florida) until she went to sleep. She also made her sleep through several feedings. Now the baby wants to sleep all day and she is up all night and wants to eat every hour at night. Any tips on keeping a baby awake during the day? i’m waking her up to feed her every three hours during the day but she is passing out mid feeding and not wanting to wake up even to burp. I’m pulling my hair out of my head.
