Here's a breakdown:
* Primary milk source: They rely almost entirely on their mother's milk for the first 12-18 months.
* Transition to solids: They start experimenting with solid foods around 18 months, but continue to nurse until about 2 years old.
* Weaning: While the process of weaning can start earlier, most baby elephants fully wean around 2 years.
It's important to note that this is a general timeline, and individual elephants may wean earlier or later depending on various factors like their health, their mother's milk supply, and the availability of solid food.
