Question: I'm concerned about my baby's development. He can't stand on his own without support and isn't crawling yet. I suspect it might be due to weak bones, so I've been giving him supplements like calcium, cod liver oil, vitamin C, and B vitamins. Is there anything else I should be doing?
Answer: Good morning, and thank you for sharing your concerns. I can imagine how worried you must be seeing your baby struggle to crawl or stand on their own, even after giving supplements.
From what you’ve described, I want to gently remind you that delayed milestones can have many different causes. It’s not always about weak bones—it could also involve the muscles, nerves, or how the brain is developing. Even if your baby is getting calcium, the body needs enough vitamin D—either from sunlight or supplements—to actually absorb and use that calcium properly.
At this point, it’s really important to have your baby checked in person. A doctor can examine things like growth, muscle strength, and bone condition, and may recommend some tests like blood work or an X-ray to see if rickets or another issue is present.
In the meantime, try to give your baby some gentle sunlight each day—ideally in the early morning or late afternoon for about 10 to 15 minutes. Keep offering a good mix of foods—proteins, fruits, and vegetables—along with the supplements you’ve already been giving.
You’re clearly trying your best, and that care makes a big difference. With the right guidance and support, many babies do catch up just fine. I encourage you not to delay getting a proper check-up so you can get the answers and reassurance you deserve.
