Re: Any other suggestions??
I had a "fall off the charts" failure to thrive girl too. She was 7 lbs 9 oz at birth and 10 lbs at 4 months and 13 lbs at 6 months. I EBF until 5 months when I started adding a bit of rice cereal to her bottle. She started solids at 6 months and was 18 lbs by one year. She was a lazy nurser too and never slept through the night until after a year.
If she is wetting enough diapers during the day and growing and thriving, hitting all the milestones, you have nothing to worry about!!!
(Funny enough, my guy is 5 months and he 2-3 lbs heavier then my daughter already!)
