Hi, may I answer your health queries right now ? Please type your query here...Hi my grandaughter is almost 4 months old and for the past few days she has been spitting up quite large amounts of formula.By large amounts I would say sometimes about 15 ml and sometimes about 25 ml.It is constant though,about every minute or so.My daughter has also been giving baby Megan rice cereal for about 2 weeks now.Baby megan has about 2 level spoonfulls twice a day and then 150ml formula.Baby Megan has also been on many different formulas since birth because she washaving projectile vomiting that was coming out of her nose too.Added to the formula is colix for breaking down the lactose and the paediatrician has baby Megan on Zantac too.Could we possibly being overfeeding her,hence the sudden spitting up? Megan has a healthy weight and is growing perfectly,She only has catnaps during the day and sleeps relatively at night.Thank you Joanne
