Second child syndrome or autism?

That could just be delayed some but will pick back up. Depends on what he's delayed in and if he makes eye contact? Does he respond to his name? Look when your point or ask him to pick up something?

What areas are he delayed in?

He will respond to name and give eye contact. He doesn’t look when I point but will copy when I clap hands. Hes doesn’t talk just babbles and says mama and isn’t walking.

Personally I don’t believe in a child being “lazy” if they can’t walk by two definitely get a professional involved if you haven’t already it’s most likely a developmental delay

There are plenty of reasons for delay besides autism. If you're not seeing signs of sensory issues or hyperfixation on certain things then it's unlikely to be autism more likely global delay or something else holding him back which may sort itself out or may need further support but I would definitely be pushing for support if he's not walking or talking yet.
