Hi. My little girl will be 3 months old on December 5th. She is really fussy. She sleeps at night okay, wakes up every 3-4 hours, but I could not say the same about the day. I try to put her to sleep after 1 hour or 1 hour and a half of awake time so she would not get overtired, but she usually sleeps no more than 30 minutes. She is trying to bite fist sometimes, but I guess she have not figured it out yet. She dont like the teething ring, but if i put a finger or side of a finger she usually calms down and keep bitting it. I think that on the bottom there are two white spots. But I am really worried about her upper part of the mouth. You can see that there are some bumps and I just felt that there us a really hard spit there. It is hard like tooth, but it can not be it as it is more inside her mouth than on her gums. What do you think?
