Hi mommies, today my daughter didn’t wanted to do tummy time. We had to pick her up not because of crying but she lifted her bum up and used to her feet to kick forward while her head glided forward on the play mat. Her head wasn’t held up when she did this but before this, she could definitely hold her head up as high. Her doctor said she’s exceptionally strong. What should we do? She’s sliding across the play mat while kicking them feet forward. Is that dangerous? She’s 16 weeks old.
