my baby has been fussy that last day or so, i dont know why. he will be eating (BFing) then he just screams and crys for a bit then hes fine. he also sticks his tounge in and out like he has a bad taste in his mouth, i dont know why hes doing that! please help

If your baby is old enough.. could it be because they're teething? Or maybe when they eat they're getting a tummy ache. My son did something kind of like that, and we found out that he had acid reflux. You could try chaning the formula, and try putting some rice cereal in his formula. Good Luck!
