i went to a breastfeeding day stay program with DD at a similar age, due to low weight gains. I was encouraged to change sides more often to keep DD interested.

I did have a bit of success with this, but too much and i felt like i was force feeding her and dd began to vomit. i decided i wanted to go back to what we were doing, letting dd decide on feeds. All other signs were fine, it was just slow weight gains that were ?an issue. DD was born at the 75th for weight, but dropped to 10th for weight by 15 months.

i don't think it was ever a supply problem, i think she was just adjusting to her genetic weight over time. DS hasn't been weighed as much but has also dropped from 99th percentile to 50th for weight.

So, i agree that it's worth keeping n eye on, but there may not be any problems, some babies just gain slower than others.
