Flaky nails?

its perfectly normal that your babies finger and toe nails can become flaky and even sometimes crack, only ever cut the nails when baby has had a bath as this softens them which makes cutting them easier also you can cut in one straight line, i find baby scissors useless where as they do ordinary nail clippers for babies now, always cut straight across the nail, on toe nails you can rub some Vaseline or even sudacream into the toes and nails which will help to keep them softer, Ive had 5 children and they have all experienced this and there is absolutely nothing to worry about, just make sure you don't leave the toe nails to over grow as this can encourage natural breaking which can become sore and cut into the skin, hope this helps a little
