Our girl Tink hand three pups this round and one is very tinny they are 13 weeks old and she weighs 10-11 oz and her two other sisters weigh 2.2 pounds, as this is the first time we have had one this small my question is how long will it take for her to catch up with her sisters. She is very active and loves to play but if she dosn't eat or get fed every 2- 3 hours she get very weak, she also hardly ever drinks water. Any advice will be appreciated.

Note: Not catch up to her sisters in size I know that not going to happen, talking about the eating.
