Erica started trying at birth lol. I think she was pretty steady around 1 month. She can hold it completely now, and can lift her head/shoulders/chest off the bed while lying down. Not sit up, but like lift up. I'm sure Josh will start doing it soon tho. Maybe try lightly supporting it so that it wont fall, but make him do most the work. Just support it as backup. All babies are different. He will soon!
