Toddler formula vrs cows milk

Dh and i were have a discussion about why our 13mth old is waking so often during the night when she slept through the night until i changed from s26 gold progress 2 to s26 gold progress 3 and for the last month has woken more than once for a bottle we were reading the sugar content of the toddler milk and did calculated that it has nore than 50% sugar in each feed 16gms per 220ml thats a lot of sugar i decided to switch to cows milk hoping that we can get her to sleep through the night again any other mums have this problem
