Baby not gaining weight at 7 months

[Bardot12]

Hi all, my baby has been on 85th percentile but at 6 months seems to have put virtually no weight on in a month and has dropped centiles. He is pretty active and constantly rolling and trying to crawl and not really eating loads as doesn’t seem that interested in food. He is EBF as refuses bottle and feeds well at night and first thing but is super distracted during the day. Is this just a phase? Is there anything I can do to help? I also feel like my supply is going down because during the day he feeds so sporadically.
thank you

Yes probably a phase. If he's active and (mostly) content unlikely you need to worry.
He may be burning off more with the increased movement too.

My daughter only gained 200g between 7 and 13 months and dropped a percentile

It was put down to her appetite not matching her activity levels. She didn't engage with weaning at all and at 12 months only had the odd spoonful of food a meal. She eat her first meal at 13 months and then had a growth spurt and started gaining weight again. I was told that as long as she wasn't loosing weight I shouldn't fret. I had regular weigh ins through out and she was under paediatrician and dietician support due to allergies
