I am a worrywart mom. My daughter and I share the same birthday. Our little one already sits, crawls, stands with support, and babbles.

He doesn’t crawl and doesn’t seem to try; he wants to stand, but his bottom is too heavy and it doesn’t work. And there’s no speech at all. On Monday I want to schedule another appointment with a neurologist. I understand that every child develops at their own pace, but it’s a bit worrying…
