A hardly ever cries during the day. She's so happy, she doesn't seem to fuss at all.

But at bedtime, OMG! She goes to sleep fairly easily at about 6-6.30pm and sleeps for about 30 mins but then wakes up INCONSOLABLE! It doesn't matter if she wakes up in her crib, or wakes up on me, she cries her heart out at this point. It's unlike any of her other cries. The best way I can describe it is "rah, rah, rah" constantly. It makes her choke sometimes it's so hard. I hold her and let her cry, I've found if I soothe her too much it just prolongs the agony in the end. She does it whether she's fed or not so I don't think it's reflux.

I wondered what your babies sounded like when they're fighting sleep? Is it just their normal cry or do they amp it up a bit?
