LO is nearly 6 months old and has been teething for a month and a half. I check every day for teeth ANYWHERE in his mouth and nothing. We have an arsenal of remedies/medications/teething toys for him but teething has turned my sweet boy into what my DH and I have lovingly termed "bipolar baby." He goes from happy to angry in mere seconds and his sleep has gone from just okay to super terrible. I feel so bad for LO and I'm not sure if there is anything else I can do. Is this normal?? When will these darn teeth show up?
