Gassy Cailynn

Cailynn is very gassy for the past few days. Not sure if it is the multi-vitamin that causes it. Basically, I was supposed to get a new bottle of Poly-vi-sol for both of them but mistakenly getting the one without Iron (Charissa needs Iron supplement coz her level is quite low). I really didn't know that there are two types (one with iron and one without)...and I was rushing!!!! Dear hubby suggested that I should get another bottle with Iron for Charissa and since I've opened the initial one, I can't return and hence he told me to give it to Cailynn instead. I tried giving Charissa the one without Iron today and she seems fine. Have been giving Cailynn some Milicon gas drops and again, it doesn't seems to work. At each feeding, I will need to burp her 2-3 times or else she will struggle, unlike her previously...she can finished 4-5 oz of milk without burping! I hope she gets better soon. Poor baby!!!!
