Hello! I am a new mom, a Certified Medical Assistant, Emergency Medical Technician, Search & Rescue Canine handler, and someone who is interested in learning more about Lactation Consulting, etc. I also have 3 years of Pediatric Experience so looking at Lactation Consulting for the future seems like an interesting field. I wanted to tell you all, in my opinion, when I started to put Elizabeth on occasional bottles the only one that worked was the AVENT. By the way, I by no means am involved with selling this product. The bottle is very wide with a silicone nipple that has a large base, shaped like Mom's areola, & more rounded non-collapsible nipple. I tried several latex nipples & the Johnson's Healthflow silicone nipple before this one. Happily Elizabeth takes the bottles great now so I can have some independence, like going to an EMS conference this week. I was wondering if a baby with a history of allergies & milk intolerance could still breastfeed? I saw a friend of a friend this past weekend and she said she now uses a soy formula and could not breastfeed because of this problem. I look forward to being part of this group. Your postings are all so interesting. Have a great day! Erin Mom to Elizabeth, 5/18/95 New Tripoli, PA near Allentown
