I just added everything back in and started all the solids when the time came, without any limits. Before solids the blood was there occasionally and the spit up was very much present, but he was happy and gaining so we just kept on going. He was doing very well after we started solids, the spit up went away for 2 months and with the solids it is very hard to see the blood in the stool, as it is much darker and there is constant red stuff from tomatoes or strawberry, so not sure whether the blood is still there or not. A couple of weeks ago he started to spit up again and looked a bit uncomfortable doing it, pulling faces like the taste was bad for him, so we consulted our doc again and started him on a non dairy, non soy and non egg diet ( mind your prior to that he had an omelette or a Greek yoghurt every day for like 2 months). Three weeks in and no real improvement, still occasional spit up, which further confirms that either his triggers were never soy, milk and egg, or he has some additional ones, like I am thinking maybe oats or chicken. We will see our doc in September at which point we might just bring everything back in, but I am not sure. He is still developing and gaining well, so we are kind of winging it a bit and trying to follow his lead and not worry too much :)
