Robynne • Miscarriage in April 15 at 9 weeks and MC in November 15 at 5 weeks, now expecting our rainbow baby December 2016 🌈🎆
So I know this is not necessarily pregnancy or baby related but bare with me and this long post! 
I have a 6 month old puppy who unfortunately broke her leg a few weeks ago and has been on crate rest since, we where making good progress with training but now she's biting really bad, she thinks she's playing but god it's sore! 
And I need it stopped before the baby gets here any advice? I've tried yelping and telling her no, I've tried to redirect her attention but she gets so hyper!
