EBF and allergies

My almost 8 month old is allergic to dairy, dairy proteins, soy, squash and talc (used to bleach rice and found in many things such as prenatal vitamins). I EBF now and he's huge. He's almost always been in 95+ % for everything. I however am not! I have lost so much weight it's bad. I try to eat a lot and eat whatever I can. However there is dairy, soy and rice in everything! I am stopping BF at 1 year. That's my plan at least. His allergies are not severe and I do believe he will outgrow soy by 1 and maybe dairy a little after. My pediatrician is a moron and we are having problems finding a new one accepting new patients. I drink almond milk and I saw an almond/ cashew one that had more fat in it. Would this be acceptable to feed a 1 year old? Has anyone else gone through this? My supply is good and I would BF as long as possible but I'm just losing too much weight. I'm normally 145. While pregnant I ballooned up to 195 and now I weigh 125. I miss cheese so much lol dear god 😜
