My son is 18months hes not walking yet should I seek physical therapy for him or should I wait???

I believe 18 months, while it may seem late, is still within the normal range. Like @earthymama asked, does he show any signs of attempting to walk? If you are concerned, your first step should probably be discussing it with his doctor. If they believe it’s an issue they may refer you to your county’s early intervention program. Early intervention would have an evaluation and let you know if they believe he should receive services. Otherwise you could always pursue physical therapy on your own.

I think u should see about physical therapy/ talking to doctor I don’t think u should wait since ur son will be 2 soon

What does his pediatrician say?

Some babies are just late bloomers. I’d open a dialogue up with your doctor, do some research and go from there. I wouldn’t be worried as long as he’s at least cruising and showing interest in walking. My son started at 13 months and what I feel like accelerated walking was just having him walk EVERYWHERE holding his hands.

Yes.
