my baby completing his 6 month. he is stil not sitting.plz suggest me what to do

Don't worry.. he may sit anytime now. Is he rolling? Is he holding his head? Is he showing readiness to sit? Can he sit with support? Initially babies will support. slowly after falling..with lots of efforts and trails..they will learn. You can even talk to your doctor once.

I agree  Pls wait. Each baby has their own pace. Let it happen. In your dr check up just double check with Dr
