Flat Fingernails: Just noticed 7 months DS has a flat fingernail?

[tangent]

Does this mean anything? Is it an indication of a health problem?

my DD2 15mo has very 'wavy' toenails...[lurks in hope of answers]

I'm not sure but all mine have had flat/curved the wrong way toenails as babies and they are ok now (at 7 and 8, alhough ds'at 21 months are still odd looking)

thanks for that. it probably is worth asking the health visitor at his next weigh in, but i know what you mean, there are a lot of jobsworths in the NHS (i used to be one of them), and they might insist on investigating further just to find out he's totally fine. i suppose i have to be prepared for that if i chose to mention it to the GP or health visitor.
