I have a 4 week old baby (but he was born at 42 weeks so does that make him 6 weeks old indevelopment terms?) he has feeds of 4 oz of number 1 cow and gate formula. I have noticed the past week he spits up and is sick not quite projectile but enough to comcern me. He will also be in his moses basket and I willl wait for him to drift off and he will then his face changes there is no sick or spit up and it sounds like it stuck in his throat and he cries this can happen if he sits up, is lying down or in a seat. I rang the health visitor and she was not much use other than bring him in a day early to get weighed!? I tried the number 2 milk today for hungrier babies it says from birth on the pack but have heard people say dont use it until so many weeks old ? I cant remember when?! I think it has something to do with the kidneys and how they function. Well I tried him with one feed of it today and the milk stayed down so I tried a second feed it seemed to stay down too. I would like to try this for a few feeds a day and use the number 1 milk the rest of the time. Im seeing the health visitor on Wednesday but wondered if anyone else had similar problems? thanks
