Hi! I'm new here and have been lurking for quite some time now... But wanted advice from you folks.

My pedi has been concerned about my LO's weight gain. He's been growing, but has been around the same weight for about 2 1/2 months now. Which is around 18lb 13 oz.

Recently I have been eating a lot of raw and drinking a lot of green Smoothies, which my LO really loves! When this was mentioned to my pedi (Becuase he wanted me to start giving my LO meats for iron) I mentioned that he loved drinking green smoothies, and he basically dismissed it saying that meats would be a better source of iron... .I was dumbfounded. And then I said, that I wanted to give him fresh fruits and veggies (the ones he could acutally chew) instead of his jarred food, and again... He said it maybe once a day, but he'd rather him have the jarred food... THEN on top of that, he wanted me to quit breastfeeding and start giving him formula.... This one took the cake... By then I was really upset and just couldn't believe what I was hearing.

Anywho... The Doctor wanted to get blood work done to make sure he wasn't anemic (Mind you they checked his iron levels 4 weeks ago and they were above normal) and urine samples. DH and I went along with it becuase we thought, hey maybe something is going on, we need to know about. Well after 20 minutes of them poking and proding my poor little baby and them still not being able to get in his little veins, enough was enough. They wanted us to go to a Children's hospital to try and get the blood again, but I can't bring myself to put my son through all that again when all I see is a bouncing, happy, energetic, healthy little boy.
DH and I decided that we are going to pump the little guy full of fresh and healthy food (no more jarred food or unhealthy "adult food") for the next month until his 12 month Well check up and if he still doesn't gain weight then we'll talk about additional tests.

Thanks for sticking through my rant. My question and plea for advice is, what are some nuts and seeds I can put in his smoothies to give him healthy fats. I know I can up his intake of avocado and I will start steaming some veggies for him to munch on throughout the day... Fruits, he takes with no problem (He already has all 8 front teeth and a molar) I just don't know if I can stick the seeds and nuts straight in the smoothie and lt them get blended with the rest of the stuff or if it will be best to grind them up with a coffee grinder first and then give it to him. Thanks so much in advance for those of you who got through this and respond!! Any other healthy food ideas are greatly appreciated.
