Is this normal for a two-year-old boy?

Are you sure there aren't any developmental red flags going on? Does he make eye contact or have any repetitive behaviours? How well does he communicate with you or peers? Could be lethargic for mineral deficiencies, but a child with no smiles and blank looks concerns me. Does his hearing seem o.k.? Can he follow some directions, or doesn't comprehend at all? Keep an eye on his expressive and receptive language abilities, and how he relates to peers, and explores the toys. Perhaps he's a terrible sleeper at night at home, but keep your eyes open.

He doesn't say one word all day, other than Mommy sometimes. He doesn't often make eye contact either. If I ask him to do something I have to ask him three or four times.

I would still tend to lean to a low iron or thyroid before the autism/developmental delay route. If he is falling asleep and lethargic it would more likely be the iron/thyroid which would greatly affect his ability to interact and speak and engage. Children with autism and developmental delays, in my experience, tend to be difficult sleepers and wouldn't usually just doze off.

I have low thyroid myself and it does put you in a zombie state where you just feel like your body is made of lead and the energy it takes to follow through with a request can be a lot. So...imagine that on a 2 yr old..in a new environment and what you describe behavior wise makes sense to me.

I'd start there before thinking autism.
