I did not breastfeed my first 3 boys and I regret it a lot now when I look back. I had no reason not to, but I made excuses. I understand it's not for everyone, but for me I should have given it a shot with them. Breastfeeding my last 2 children has been a great experience for me. It has it's challenges, but the benefits and the bonding is so worth it.
Here are some sites for information on breastfeeding.
Now on to Car Seat Safety. My views on this subject have drastically changed over the past couple of years. Between my own research and recent studies I have read about, I could not help but change how I feel about it.
I have all 5 of my kids in 5-point harnesses, even my 7 1/2 year old. Now I don't think everyone should have their 7 year olds in a 5 point harness car seat, but my son is small for his age and he's WELL under the weight and height for the car seats I own. He also has no problem still being in a 5-point harness, in fact he always says he's safer and he's happy about it. All 4 of the boys are in Radian 65 and Radian 80 car seats. Gracie is in a Graco Snugride until she grows out of it and we already have a Radian 80 waiting for her (a pink girly one of course!). Sunshine Kids Radian car seats were my choice for several reasons, but the main reason being they are the slimmest seat on the market so they are able to fit 3 across in the third row of my 2008 Chrysler Town and Country. They also have a steel frame and are one of the highest reviewed seats for safety.
Keeping my kids in a 5-point harness for as long as possible isn't the only thing that has become very important to me. I am also rear-facing until at least 2. Children under 2 are 75% less likely to be seriously injured in a car crash rear-facing. Those statistics are enough to make me keep Zayne rear-facing until he's at least 2 and the same goes for Gracie. I absolutely do not look down on parents who choose to do things differently. These are choices that make me feel comfortable and I like to pass on the information I have :).
This article says a bit about the study.
This site is very helpful when it comes to ALL things car seats! Safety, brands, reviews etc.
