not cathe but suggestions i have gotten in the past from others is
1-make sure you do cardio to burn over all fat, you may have a six pack but some fat may be covering your progress
2-make sure form is proper and that every rep is strong. "make every single move count"
3-give it time, sometimes after babies our skin stretches and it takes time to get back to normal so that may hinder your results as well
4-give your abs rest, they are just like any other muscle. don't work them hard everyday without proper rest. 2-3x a week should be good(this could be different for everybody, you have to play with it to see what works for you)
5-make sure you work lower back to, helping proper posture will help you stand up straighter and give the appearence of flatter abs
the last one is myself, i have some defintion in my abs but when i slouch just a bit i lose it. not to mention doing harm to my back. these are just suggestions i have gotten myself and just wanted to pass along.
