How can Shari Stamps's tips improve tummy time and floor activities for babies?

She emphasizes the importance of quality over quantity during floor time. This is a workout for your baby, so it's about strengthening their whole body, stretching their spine, lifting their head, and more.

She suggests adding engaging items like a crinkle square or visual cards, but advises against too many toys or those with flashing lights or sounds.

For babies who are tripod sitting, she recommends continuing tummy time for a strong core and spinal stretch, practicing the transition from belly to seated and back, and giving your baby stackers or tall shaker toys to help them sit tall.
