DD 6 weeks old - hasn't settled at all today and screams unless boob/finger in mouth

[littleduck]

Not quite sure what to do - poor little DD is horribly unsettled today, usually settles to sleep quite easily between feeds and sleeps well until next feed due.

Poor little thing has only had two short naps since 10am, is yawning her head off and clearly overtired but will only stop crying if I either feed her or put my little finger in her mouth. I left her briefly to have a shower and she became hysterical.

I know they can be cranky around 6 weeks due to a growth spurt - am just not sure what she wants, food or comfort. She sucked on my finger without fuss and didn't seem desperate for food but perhaps she thought if she sucked on the finger long enough some nice milk might come out.

I don't like to see her this upset and want to meet her needs but am really not sure what her cries mean and what she wants. She sounds frightfully cross though! It is getting rather wearing and any suggestions as to how to soothe her would be really gratefully received. Am hoping she will settle tonight at least but on present form not looking likely

have you tried swaddling to calm her down? or a car trip/pushchair push or sling? sorry cant help much- have a 4 week old and feeding usually settles him, otherwise i try one of the above (or a dummy).
