Over a bit

The baby likes to play with his bit. I thought this was a pretty normal thing and didn't think much of it until I noticed his entire tongue was sticking out to the side and wiggling around. The baby likes to get his tongue on top of the bit. So I unbridled him, re-bridled him, and stuck my finger in his mouth holding the bit up so he couldn't get his tongue over the top. This obviously was not a long-term solution. So I tightened the bridle a lot, so he was really grinning, and he was really trying but couldn't get it over. (I also noticed the 5" bit is too big and I'm going to have to get a smaller one. I'd like to get a French Link, do they come in full cheek?) Until I got on. Looked down, and there's his giant tongue wiggling out to the side. I don't know how he fits the whole thing in his tiny head. I just rode anyway- we did a few laps each way at the walk, and one lap each way at the trot! He jogged along like a western pleasure horse with his head down on a loose rein. At the advice of Katie, who found him for me at the track, I'll put a figure 8 or drop noseband on next time and see if that helps. He was a gooooooood booooooooooooy today.
