I breastfed my DS exclusively for 4 and a half months and then combined with Aptamil for about 2 weeks. After that I ended up only giving formula as I found my milk was reducing and DS was turning away every time I tried to breastfeed. It was also hard to juggle his feeding with school run for my DD. I had fed my DD for 3 months and felt fine when gave up, but this time round I feel really guilty and that I should have persevered until at least 6 months, as all the articles I have read on the internet say how inferior formula is, and that should BF for 6 months exclusively. Does the fact that I didn't reach the 6 month mark mean that any benefit is now wiped out?
