Flaking belly skin! HELP!

My daughter is now 3 1/2 months old and ever since I delivered her my belly skin has been soooo dry and flakes sooo badly! I have no idea why it’s still happening. I’ve tried exfoliating and using really moisturizing lotion and just when I think I’ve got it beat it comes back a couple days later! Does any else have the same problem? Anyone know what else I could try?! It’s driving me nuts and it’s quite gross on my opinion!

That one spot is red because I was scratching before I took the picture.

TIA!
