Hi and welcome-im new also
I feed Bella 4 x a day 7am, 12pm, 5pm and a small meal about 8 although we are phasing this out as she isnt eating much of it now.
As for the nipping, yep having same troubles here I just keep rewarding/praising when she is playing nicely and say owww really loud when she bites and walk off-I found yelping like a pup excited her more. Some times she remembers to play nice but others gets a bit carried away but she is learning. Im finding the bites to the arms the worst when she is having a snuggle xx
