Breastfeeding is the way to go both the health benefits for the child and mother, plus all the positives for the environment. No energy consumed (warming bottles, producing bottles and formula.) No water used in the preparation of formula. It is all ready and set to go.
Now I understand the personal choice here. But I am also certain that one should take into account all the benefits when making that choice and they far out way the benefits of bottle feeding. Some mothers cannot breastfeed. My first child was a natural and I breastfed for 22 months. My second child was a little more difficult. It was very challenging at first just to get started any much of my support suggested just switching to formula. That was not an option for me so we continued and struggled and persevered until she was about 41/2 months and then I started to supplement with formula. The thing is I never gave up and even with supplementing I continued to breastfeed her until she was 18 months old. My newest arrival has taken to feeding quite well and I look forward to another 22 months of breastfeeding her.
The point is breastfeeding is the "green" way to go. It is good for mother earth. The mother and the child.
