I was just talking about this with my husband. He is from Eastern Europe where breastfeeding is very much the norm. Formula wasn't widely available for a very long time there. So, he was exclusively breastfed until 7 months or so and his mom continued BF'ing him until almost 2 (he thinks.) I, on the other hand, was reading through the baby book my mother just found and gave me. I was astonished reading through it! I always knew that I was formula fed. My mother only BF my older brother for two weeks and stopped due to sore nipples (and she was never informed of or referred to any type of lactation specialist.) She never tried to BF me. At two months I was started on rice cereal and whole milk! By the time I was 6 months old I was done eating baby food completely and was eating only "table scraps" according to my baby book. Eeek! Mom was giving me ANYTHING from the table and I ate what the rest of the family was eating, no matter what that was. Knowing what she knows now she would never repeat that, but she was never informed otherwise. She said that she was following my doctor's guidelines for introducing new foods!
I was very colicky as a baby. I've also struggled with maintaining my weight for as long as I can remember, which I know are both direct results of the way I was fed as a baby. Luckily those are the only struggles I've had to deal with.
