Baby Weight

6 weeks ago I gave birth to a gorgeous little boy! He’s a very happy smiley boy, however I’m at conflict with two different medical opinions... His health visitor is concerned he’s not gaining fast enough but his GP is not at all concerned and said he will just see him at his 8 week check. Baby is exclusively breastfed, has an average of 4 yellow dirty nappies a day and an average of 5 wet nappies a day, he has great muscle tone, settled after a feed and has times in the day where he is alert and starting to smile and coo 🥰

Im just confused to who I should be listening to, GP says to carry on as I am but HV says to start introducing formula 🤷🏽‍♀️

I will insert an image of his weight loss/gain and a sweet picture of my smiley boy!
