Castle - oh asleep on the bathroom floor, that's scary when you are that tired! I'm so sorry - sending lots of empathy your way. My whole family suffer when I'm tired, so my DH tries to let me sleep in or have a nap once on the weekend. Your poor little munchkin though, sore head, sore tummy and bum. Hope you and the baby don't get it too.
Tiggy - hope you get some answers and everything starts to get better, it must be very draining on you both physically and emotionally.
