Hi Gilana! Yes I do have girl/girl twins! It's awesome isn't it? And it is a LOT of work!!! I felt like I spent 99% of their awake time feeding them, etc. so I cannot imagine how difficult it must be for you with the GERD and milk protein allergy. One of my daughters had a questionable milk protein allergy but it ended up not being a huge deal. My twins will be 2 at the end of January! Today I thought I was going to throw them out the window!!!

just kidding, but they are so darn cute that it keeps me going! Are yours identical? mine are fraternal...do you ever go on twinstuff.com? It's a great resource for moms with twins!!
I'm sure your pediatrician is wonderful...I didn't mean to imply otherwise. Our pediatrician was also excellent, one of the best in our area. There are a lot of misconceptions/conflicting information out there even with the best of doctors and sometimes its worthwhile getting an opinion from a specialist when things like ulcerations occur (because they deal with them every day and sometimes they can affect the final outcome) That's why this website is good because it will help parents like us to be more informed and then we are more equipped to ask good questions of the doctors. However, YOU are the best judge of how things are going with your child and just trust your instincts. If it seems to healing up and all seems well, then go with it. You could also send photos to a doctor on the panel here and he can tell you what he thinks. At one point we were getting conflicting information from our pedi and our specialist and I emailed the expert on the panel and that gave us lot of guidance on what to do for our daughter. It was good to get that outside opinion. So maybe you could do that if you weren't sure.
Good luck with your twins! If you want to get in touch with me on facebook let me know (and we can swap twin photos!)...That's always fun! Keep us posted about the ulceration!
