My 4 mo old son was up 6 times last night!! He usually sleeps 12-13 hours at night with 1-2 feedings, but he wanted 6 last night! So frustrating! I don't expect this to be a habit, or I hope not, but it made me wonder if he could be starting to get teeth. Usually when he wakes up at night, he just fusses and moves around and that's what wakes me, but last night he was actually crying when he woke up. He also has been biting on everything, toys, our fingers, his fingers, etc, and drooling more. I felt around to see if I could feel any teeth, but I didn't feel anything. Is it too early to start getting teeth or was he just having a hungry night?? I should also add that he doesn't at all seem more fussy during the day. Just curious! Thanks!
