11 week old - low weight gain

[Katiegirl]

Hi all. I am looking for some reassurance. My son is 12 weeks today and I had him weighed and measured and his growth has slowed down in the past 3 weeks. His weight has increased by about 76 grams per week for the last 3 weeks and dropped from the 40th to 25th perc on the weight graph. The MCHN suggested I try comp feeding him with formula which I really don't want to do. He is generally a very happy, giggly and contented baby. He sleeps well and in the past 2 weeks has actually dropped from 6 feeds (he has been wanting 6-7 feeds almost since birth). The past couple of weeks he has dropped to 5-6 feeds. I think I will introduce a rollover feed around 9pm.

I do offer extra feeds but like his sister if he doesn't want to feed he gets angry and neither of my babies have been comfort suckers. The exact same weight issue started with my daughter at 12 weeks and she is fine - she is petite but healthy.

Should I be worried? I wish I had not had him weighed as I was so happy with how he is going - and now I am worried and have the 'formula' idea hanging over my head which I am not happy about. Any advice?
