T.S.
Your baby is completely normal!!!
At 3 months, breastfed babies very typically want to nurse between every 2-3 hours during the day. Remember, breastmilk is a very complete and digestible food--designed especially for your particular baby at her stage of life. Because of this, her little body is very efficient at using it. The smiling and playing and "flirting" with you is one of the beautiful gifts you and she both receive when you breastfeed. Nursing her is not just a feeding method, it's also an emotional and spiritual growth experience for your baby.
You may feel like very little milk is being consumed, as you put it, because now that your body has regulated, you no longer get engorged the way you would when she was just a few weeks old or even for the first month or two. Don't worry...she's still getting plenty of milk, even if your breasts don't feel as "full" as they used to. That's also normal.
Enjoy this time while you can! And just wait for the "acrobatic nursing" at 6-18 months!
