Hi supa - Does Tia seem to be in any pain? Is she going red in the face or seem to be straining? Maybe try ele-v's massage trick after a nice relaxing bath. Other than that she may just be hungry again. Has it been hot where you are? Sometimes I find that Hannah is quite unsettled even though i have done everything - then i just feed her again to calm her down. This usually works for me. Could she be tired. I know Hannah also wriggles and does her little kitten cry - short little screams (so cute) when she is tired. I take her somewhere quiet and put on some soothing music to help relax her. I hope she settles for you.
re the bleeding - i'm not too sure - maybe just call your midwife for some advice if you're worried.
I hope you hear from your mum and dad soon and find out why they left without saying goodbye.
I probably haven't been much help to you - but I know what it feels like when everything seems to get on top of you. Sleep deprivation doesn't help with that either, does it.
