Hugs hun!! I know how family can be!! My mom thinks I'm crazy b/c I have Patrick on a routine!
Just remember you are her mummy and YOU know what's best for her!
It does sound like teething you know? Every baby reacts different to teething. Some STTN and have horrible naps, some have great naps, and crappy nights; and some have crappy naps, crappy As, and crappy nights!
So, I guess Amber gets more pain during the day!
Keep giving her the teething gel and powders before naps and bedtime.
I'll be right here waiting for you once your family goes away and you want to get Amber back on track!
