slow weight gain

morsey2011

At DD's one week appointment, she was down 8 oz from her birth weight. She has plenty of poopy/ wet diapers, and nurses really well. Today was her one month appointment, and she's 3 oz over her birth weight. I wasn't able to go to the appt due to a virus. DH and my MIL went. She didn't see the normal pedi, and saw a nurse practitioner instead. She told them that DD wasn't gaining fast enough. I posted on here yesterday about DD sleeping long stretches ( normally 5 hours, 8 hours Saturday night). The NP wants us to wake her up every 3 hours during the night. I guess my question is for other moms whose LO's gained weight, how often would you wake your LO?
