Kicked out of daycare!

I know you're thinking to yourself, "how could this happen?" But it did! My son was kicked out of daycare. He has developed a habit of biting, which I honestly don't know how or where he got this habit. He doesn't ever bite with us, and when he does he gets in trouble. But for some reason, with other kids, he just can't stop. I don't know what the heck is wrong. Anyway, another parent became upset that my 18 month old bit their child and the babysitter told us not to bring him back! Just out of the blue! In one day and out the next. How do you think this makes him feel? I am completely stunned because how could they possibly think that he is doing it on purpose!?? He is 18 MONTHS OLD!! He doesn't understand! But, the way I figure, he must have learned this defense mechanism because of other kids. So, it's probably better we had to get a new babysitter. I'm just incredibly PISSED OFF. Not because we had to get a new babysitter, but because they treated my son like he was completely expendable. In one day and out the next. What a way to treat a baby. (Although I do understand why the other parents were upset. I wouldn't want my child to get bitten either. But does he need to be kicked out of daycare and treated like an outcast??? The answer is no.)
Anyway, on a brighter note..... we found a new babysitter and she is wonderful. It also helps that she is LDS. I believe that this was truly a blessing in disguise. Hunter's entire demeanor was different when we picked him up today. He was refreshed, energetic, and happy. He took a 3 hour nap, which helps tremendously! He came home and played with us and snuggled me for an hour! It was a wonderful evening tonight!
