birthday body 😍

Brittany 💅🏽👑
So my birthday is in October I wanna loose 20 pounds before my birthday . I wanna get my stomach flatter & my thighs thinner . Any tips on how to do it ? I need like a fast most effective way . I'm also a single mother who works and my daughter is not in no daycare so I have her all the time except when I'm at work . . .
