DS had his 2 month check up last Monday and the doctor said he wants to see him gain faster before his 4 month check up. When he was born he was only 6 lbs, and at his check up he was 8 lbs 6.5 oz which I thought was a good weight gain. But he is only in the first percentile for weight. I am EBF and feed him on demand so I know he is eating when hungry, and I don't stop until he lets me know he's done. I don't know what I'm supposed to do to help him gain more! 
So my question is this- does what I eat affect the fat content of my breastmilk? I mean, if I start eating fattier foods, is it going to make him gain faster? I am eating very low fat foods because I want to get this baby weight off. But I am getting the recommended calories also, just in a healthy way. I don't want to eat fatty foods because I feel like what I eat right now, so is he, and I want him to be healthy!                 
                             
        
Re: How does food affect breastmilk?
I don't think eating fattier foods will do anything to help him gain. Are you eating from all the food groups? Healthy fats like nuts and things?
My firstborn fed on demand but I had to supplement because he wasn't gaining enough. What did the doctor suggest to help weight gain?
Just to add some perspective on the weight gain or lack of, and please know I had a lot of difficulties with ebfing my first two, it's just easier for me/my body the third time around: BabyE was 7lbs12oz at birth, went down to 7lbs1oz leaving the hospital and today at 3wks3days we weighed him and he is 10lbs3oz with a onesie and diaper on.
He only eats off one side and I pump the other side. He also won't latch without a nipple shield so I know it isn't latch issues. Both DH and I are smaller and I was only a 5 lb baby when born, so I guess I wasn't too worried about it! He's meeting his milestones and is happy and content.
Yes I am eating from all of the food groups. I eat almonds quite often, chicken, lean beef, tuna, peanut butter.... Our pedi is very pro EBF and didn't even suggest supplementing with formula. He said to try feeding DS more often, but if I try to feed him when he isn't hungry, it just makes him mad.
I'm great fed baby should gain 1-2lbs per month. It looks like you just made it. I can understand your doc wanted him to gain a little more than the bare minimum.
Is he waking up at night to eat? If so, how often?
He was waking up once, sometimes twice a night. This week though he has started sleeping through the night (which for us is 4:30-5AM)
I've been back to work for 3 weeks now so I pump while I am at work, and also while I am home so that I can stockpile in the freezer in case my supply does drop. I want to give him breastmilk for as long as I can. I've met with an LC already and he is eating what he needs to eat. When he drops off he does it on his own and is happy and content, which I would assume means he's full. I'm actually pumping more now than when I first started back to work.
