aww hugs hun
i wish i could offer a magical solution, but there isnt one-the best thing to do is WHAT IS BEST FOR YOU!!!!
There is nothing wrong with DD wanting a feed all the time- If it suits you- perhaps she is having a bit of a moment and needs more bbs at the moment.

If it is a problem, then perhaps it might be time to look at offering more water throughout the day in a sippy cup, or space out her meals a bit so that its food and then boobs. Perhaps even offering more snacks as well- say every two hours.

Boof doesnt eat a huge amount either some stages- its not use forcing it- when they want it- they will take it.
Just remember that she wont be 21 and still having booby's- it is such a short time in her life!- hang in there you are doing an awesome job!!!!
