Is she teething? Maybe having tummy issues? There’s gotta be something going on especially if this is just now happening. My sons slept all night since he was 2 months old but went through a period of 2 weeks where he did the same and come to find out it was his teeth. I swear by Amber necklaces. He always wears one and I lost it for 2 weeks cause I took it off for some reason but after putting it back on we haven’t had any issues since. No fussiness at all.
