Why is my baby swimming during tummy time?

Is it normal that my 5 month old looks like she’s swimming during tummy time? She wasn’t doing this a month ago. Most of the time she seems content, but occasionally she gets really frustrated. What should I be doing?

Hi, this is a reflex that emerges around now. It is typical. You still want to encourage her to prop on her arms and to use her arms though. You can play with her over your legs or over a cushion and have a toy on the ground or in front of her to play with!
