Tummy Time

My wee man 10 weeks, HATES tummy time, but we do it anyway. But he doesnt engage his arms i tuck them under as to get him to use them but ends up tantrum ing them out and just lays there and screams...so sad hes so advanced with other motor and mental things but this holding head up from tummy has him left behind. Any advice youtube vids u can recommend ive watched a few to try new things but nothing seems to be helping.
