from childhood up - с (самого) детства
Детство от рождения до какого-то определённого возрастного предела ("I had a really good childhood up until I was nine, then a classic case of divorce really affected me"; "I dont remember my childhood up until i was around 11"; "The ability of the eyes and the brain to work together develops throughout childhood up to the age of about 8 years").
