Right Age For Crawling, Walking and Potty Training
My step-daughter is getting pressure about her 6 month old baby's development abilities. The dispute is about the right age for crawling, sitting and potty training.
Her mother-in-law is constantly telling her that at 6 months her baby should now be trying to crawl -- since 5-1/2 months he is already sitting up by himself. She also says that both of her kids were walking at 9 months. And they were also potty-trained by 1 year old. Obviously this makes my step-daughter feel resentful.
My question is: What are the right age ranges for babies to start
3) being potty trained
