Will you pass your bad habits on to your children?

This is something that I am going to be very passionate about for years to come,
After growing up being allowed to eat junk food, take away and microwave meals,
I am still to this day a seasoned salad dodger and chocolate eater!
It's not something I am proud of but it was how I was brought up and some bad habits are extremely hard to break!

I grew up being overweight with led to me having lapband surgery when I was 18 years old,
by no means was I massively obese but I was depressed and after attempting to lose weight for a knee reconstruction and losing all of 3kg in 3 months my mother and I decided that it was time for a huge life change and that's what we did!

I believe strongly that my mothers choices of what to feed me when I was young did effect how I eat now but I don't blame her for any of it.

I now have a family of my own and yes, sometimes cooking up some processed frozen food looks like the easy way to make a quick meal but I don't want my children growing up believing that it is ok to eat junk all the time.

My son eats a lot and is just like my husband with a very quick metabolism, but, That doesn't mean I feed him junky things.
He eats Fruit, Veggies, Salmon, Bread, Pasta and Salad.
He still drinks some milk but now it is mostly water.
I don't feed him chocolate or lollies, He has some junk food when attending birthday parties but at home it all in moderation.

I don't want my children to grow up with the bad habits that I have passed on to them.

Today I was going down my facebook newsfeed and came across a picture of a fellow mum's (with a lapband) 12 week old son being fed spoonfuls of nutella!
Why I believe parents have rights to do what they feel is right for them and their child, 
I don't believe that you should be feeding a baby nutella out of the jar,
Do things like this set children up for bad eating habit later on in life?

I would love to hear other peoples opinions on this subject!
