Hi my dd2 was a very slow weight gainer, she was diagnosed with a rare blood problem at 18 months but otherwise is perfectly fine, she only gained 350grams from 6 months to 12months. But now is a normal size for a 5 yr old.

My little one at present only gained 150grams form 7 to 8 months. I think if they are happy, health and doing what they should all things are fine she may have just had a slow month and then next month stack it on.

My daughter3 at 8 months is 7.5kilos and was 4.155kilos born.
