Your boy seems to be tiring easily because he loves to play. I don't think that the teething has any effect on anything other than the ears going up and down. Maybe make sure that he is eating enough and give him a boost of nutrical. Do keep an eye on him though to make sure he doesn't crash. How old and how big is he? Also what type of food is he eating. I find that with these little guys the higher quailty and organic foods are best unless you can do the home cooking.
