Oh dear I had no idea there was such a big potential for debate about this!!
I started DD on tiny amounts of puréed veg and apple/pear from 17w. She always hated her bottle and would struggle through it, she did have some reflux and I think some of it was just plain old boredom with her bottle. I used to watch my sister's kids devour bottles with gusto and DD could barely be bothered, it just wasn't something she enjoyed.
We are now a month in from starting puréed veg (now twice a day, still only around a teaspoon maximum each time) and she is happier than ever. It has even made her a fan of bottle feeding, she now finishes each bottle happily. She loved the purée on a spoon from the word Go. Absolutely delighted by it.
I am incredibly careful not to over feed, I have stopped each time when she would go on for a good while longer. The slightest sign of disinterest and I i stop immediately.
I am still assuming she needs ALL her calories from her milk; the purée is just for taste and for getting to experience food.
As soon as she can properly hold stuff (that said, she is grabbing the spoon from me every time) we will start proper finger food etc.
I felt instinctively that it was the right thing for my baby; I would never have weaned before 17w and am not giving her anything but pure veg or fruit.
Reading this thread though I am now doubting myself!! I didn't think it was so complex a subject!!
Really hoping I have done the right thing...
She loves it so much, it has turned miserable feeds into happy ones...
