My almost 3 year old has been walking for 2 months now and doing a great job by herself considering all of her issues. For the last two weeks suddenly she stumbles constantly and walks around bumping into everything and constantly falling down (it's as if she were drunk and walking). She has NEVER had this problem and I know she hasn't been walking very long but she was walking perfectly for almost 2 months before now!
She also for the same last two weeks has been having her fingers in her mouth and CONSTANTLY grabbing and touching her tongue. She has never really "mouthed" or chewed on anything but ever since she started being really clumsy, I can't keep her hands out of her mouth.
Does anyone have any ideas what could be causing this? We have already seen the chiro a couple of times thinking she was out of alignment and she has been adjusted and still, no help. Any advice would be great. Thanks!
