"After birth, it’s possible to diagnose this disorder with ultrasound technology in the case of newborns. Older children and adults will need to have an MRI scan in order to confirm the presence of spina bifida occulta, and then work out a treatment plan if necessary."
Wonder if he doesn't qualify as a newborn anymore for the ultrasound detection.
Interesting too I was reading that it can cause weakness, numbness, loss of sensation in legs. Again, clearly if Daniel has it its a super mild case, but I remember when he was about 4 months old he wasn't really supporting his weight on his legs (honestly they just collapsed under him like jello when we tried to stand him up). I didn't think about it much until I saw a bunch of babies around the same age who all liked standing and jumping on their parent's laps. Granted, we worked with him and within 2 weeks he had enough strength to stand on his legs and now he has a TON of strength in his legs... but that was on the slow side to develop.
