Hello. Could your children have something like this? Tell me what it is? It protrudes like a bump, but soft, and when you press on it, it causes discomfort to the child. We're 1 year and 2 months old, we don't walk yet independently, but we're trying to stand up, learn to maintain balance. We went to an orthopedist at 5.5 months, at 8.5 months, either he didn't notice anything or didn't see anything wrong.
