Hello,

I had a similar situation with DS, born at 4040 grams but by 4 months was only around 5500....no weight gain in previous six weeks & dropped from 75th percentile to 3rd.

We saw Paediatrician to rule out any health issues & thankfully there were none, just an undemanding baby. I was feeding him six times in a 24 hour period, now I feed him 10 times. He is now just over 5 months & last week weighed in a 6310 grams...gained 240 grams in the previous week.

I posted about this issue & had lots of great support & advice from people who have had a similar experience. See at link below:

I hope this helps.
