My child is 2. 5 but is the size of a 3. 5 yo. (40 lbs.) so he is very large for his size and strong so mentally be prepared to know that lifting him and carrying him is a chore. He is very loving wild and is right in the middle of the terrible twos. so discipline structure and behavior is the most important thing for us right now. . Additional needs include being comfortable with pets. Flexible start date.
