Tummy time should not result in crying. There are so many different ways we can build strength, balance and body awareness (and prevent flat head) apart from tummy time. Firstly try micro sessions of tummy time (of what they can tolerate without cryin) and baby carriers. Also try picking up your little one by rolling them to the side first.  If you are still stuck try downloading our Ultimate Tummy Time Guide or joining the Baby Play Academy (the ultimate tummy time guide is in their for free!).
