Ridges on nails?

[Lulu_Laroo]

I've noticed Poppy has vertical ridges on her fingernails. I know this can be a sign of vitamin deficiency in adults, but what about babies? I'm getting her weighed tomorrow so will ask HV then, but in the mean time thought I'd pop on here and ask if anyone knows if it's normal or not.
