The right exercise

Hi,

I am 29 years old, mother of two wonderful little boys and I have this baby pooch that I can't seem to get rid of.  I do yoga, dancing etc.  but it's just not going anywhere.  I would say I am a healthy eater too.  I mean I do eat some sweets once in a while but only in moderation.  I'm not sure if I want to loose more weight though.  I am 5'6 and I weigh 114 lbs.  I think I'm pretty skinny but I don't feel like it everytime I look at my bottom belly with all that streched skin and fat.  My jean size is 24 or 25 but my baby pooch is sticking out but I can't wear anthing bigger than my normal size because it would be big on me.  Is there a right diet and exercise  that I should be doing? 

Please help.

Thank you.
