Normally I would agree, however in this particular situation, I feel like it came across as negligent parenting and being inconsiderate to your friends. You left your unseen baby, Halley, with your friends for hours and you didn't feel the need to check in on how your other daughter is doing? Not to mention, you don't thinks it is necessary to let your friends know an ETA on how much longer they have to "babysit" Halley? Even though Amy, Sheldon, Raj, Penny and Leonard apparently have nothing better to do than spend their entire weekend at Howard's house, at some point they will have to leave to take care of personal matters, go to work, etc. Finally, at this point, they are much closer to their friends then their own family members.
Another pet peeve, is how easy it is take care of babies in TV land. Really, Halley was asleep the entire time the gang was there? She didn't need to eat, have a diaper change or play? She NEVER cried? Bernie sure recovered quickly from her delivery and 8 stitches. I guess she isn't nursing, so that helps with getting sleep. I wish my babies were as easy to care for as a TV baby.
