Poor thing it's awful seeing them so upset and they are experts at pulling at our heart strings!
First night I patted and shhh'ing for 2 hours! Next time was 45 mins, next was about 20. By day 2 she was no longer crying, just whinging then by day 5 she'd smile at me lying there then close her eyes. It's exhausting work and so many times I nearly gave up but I soon learnt her cry from her whinge.
We flew to London 2 months after teaching her to self settle and she'd no longer go to sleep in our arms - that whole 24 hours I cursed myself for teaching her to sleep. Ha!
Hang in there, I know it's annoying hearing "be consistent" but I think it works as it doesn't confuse them.
