My daughter is 7 months and the bathroom scales seems to say she is 18.5 pounds. Not sure how accurate it is but can't be that far off as it's rig in my weight. She eats 3 meals a day plus 5 or 6 breastfeeds. Is this an ok weight ? I have an appointment with the hv this afternoon (for my older son) but since my baby will be with me the hv will probably suggest weighing her and I'm panicking now because my other three were MUCH bigger at this age ( but were bottle fed from birth).
