Thank you ladies I will be calling our gp tomorrow to make an appointment, I'm kinda glad my intuition to get it looked at is agreed with so I know I'm not being a OTT itms.

Blackrose, I would give him purees/mashes, but he doesnt really let me spoon feed him. I can give him breakfast, and a bit of yogurt but thats it really. And he doesnt really eat a lot either, milk is definitely his preference. I will try offering even smaller meals more often. Although he does usually just throw food if he isnt ready to eat lol, so I dont know how that will go.

And re sleep school, I am thinking its time to talk to someone about it. A few weeks ago I looked over some school websites and picked a few settling suggestions and gave them a go, and he was doing really well. Then we had to go away for 2 nights and since then he will not settle without feeding. Any attempt for hands on settling or me staying in the room results in hysterics and then vomiting. Tried all the no-cry books available, they havent worked so far. CC is out, on the very odd occurrence I have to leave the room with him in his bed so I can take a 5 minute breather he gets hysterical and vomits. Dont want to go that route anyway. So I guess sleep school scares me a little as I know there will be crying, which will likely distress him enough to make him unwell. I'm kinda running out of options though lol, DP cant do any settling as DS goes berserk until I take back over.
