My niece was given one as a shower gift and she had not problem. Baby laid on the puffs and grooves between each puff had plenty of room to breath. Have seen videos of her Jeannie and she rolls all over the place with it. Other day she had a large piece of bubble plastic and she and her brother just giggled repeatedly all over it. Then she rolled and put it away. Jeannnie is 7-8 months and loves her 'Itty". The quilt is a 'HELLO KITTY".
