So sorry to hear that you have lost a family member so close to Christmas. Lost my Dad quite close to the "festive season" and found it unbearable.
You are bound to be doubting yourself, with your grief, lack of sleep, and worrying about your girl.
Take a deep breath! Make sure mum is getting plenty of fluids down her. If you have to put goats milk in with her water - do so - it will help her.
And just ensure that you latch new pups on to teats every half hour until you are sure that all are gaining. You are going to be shattered, and look like a zombie. :-(
But it has to be done! Good Luck, and keep trying those pups and make sure you put loads of nutrition into mum.
