I am putting my lo on a 3.5 EASY, she can only stay awake for 1hr 30mins, I sometimes can stretch it to 1hr 40mins but she starts fussing for her bed. She goes off to sleep as soon as her head touches the mattress. Will it affect her nightime sleep if she has 3, 2 hour naps? She wakes after 45 mins but the rest of her nap, is restless as she gets her arms out of the swaddle, but she doesn't always cry. She is 17 weeks old.
