Time to transition!

So, we had a bit of a situation at Day Care recently.

All of our day care issues had finally been sorted out, and suddenly BG started acting up at school. Biting, fighting, and hitting the other kids in her class.

She actually bit one kids finger so hard she broke skin, and the kids mom was really upset at us and at the school for allowing that to happen.

My theory -- kids will be kids... but then again, BG wasn't the one that was hurt.  We'll see what my tune is when one day she comes home crying from school cause someone hurt her.

Anyways, after talking with the teachers, we came to the conclusion that she was just getting frustrated with her inability to express herself. And i noticed that she was much older than the other kids in her class. By about 4 months.  Which - granted, 4 months isn't much, but it's a lot in baby development. So I requested that she get moved up to the toddler room, but this idea was met with a lot of resistance.

BG's quite petite, so the school was worried she wouldn't be able to handle herself with the bigger kids.
BG's still a bit wobbly on her feet and still doesn't really understand how to get around obstacles without falling over them.
BG's doesn't sleep well anywhere but in a crib - and we struggled with getting her to fall asleep and nap at day care for a long time.
BG would then be the youngest out of everyone in the class (most kids aren't transitioned over to the toddler class till 18 months old) and Jeff worried about this as he never liked being the youngest in a group.

My arguments
BG started day care with many of the kids that are now in the toddler class, so they're her friends. (Can babies have friends?)
By being the youngest, BG can learn from all the older kids faster than if she's surrounded by infants that can't talk, and can barely walk.
BG is almost 18 months old, so it's not that big of a stretch.
The toys in the toddler room are much more entertaining to BG than the exersaucers in the infant room

So, we decided to do a bit of a test run, and we started dropping her off at day care in the mornings, and then she would move back to the infant room for lunch and then nap in her crib, and spend the rest of the day in the infant room.

2 weeks in the Toddler room, and she....
Knows and uses the word "MINE" all the time.
Knows the names of her friends
Knows and points to pictures of me and says "Mommy"!!!!!!!!!  <<---- this one is HUGE!
Imitates me and Jeff WAY more often than before
Get's SUPER excited when she sees that we've arrived at Day Care
Can now sleep on the floor during nap time!

All in all, I think it was the smart move. She's back with the kids that were in the infant room with her when she first started. There have been less notices about her acting out aggressively, and you can just see her learning and that's just so amazing.

Now... just to figure out how to keep those tantrums at bay.....

Oh! And Potty Training!!!  I want to start that soon, so any tips would be greatly appreciated!
