Have had to start mixed feeding with DS due to his lack of weight gain. He is having Hipp Organic 1st milk and is guzzling it. He is 12 weeks and on the .4th centile. This morning he has had 2 small breast feeds and 18 oz of formula . He has just projectile vomited all over the kitchen floor, it came through his nose and everything .
He also did this on Tuesday eve which was his first day on formula. Is it just because he is guzzling it? Its most upsetting, particurly due to my whole back story.
Any advice?
