I have a real sweet tooth and its allegedly created real problems for my mother when I was a child - I would only ever have the sweet stuff and avoided all veg, most savoury things, any dairy etc (bizarrely, I now love food with a passion so clearly grew out of it, but not until late teens). I clearly don't want PFB daughter to follow in my footsteps (I was very sickly as a child, probably due to lack of decent nutrition) so was thinking about weaning on veg only as first foods and avoiding introducing the sweeter stuff such as fruit until later so that she can get a taste for vegetables established first. Am I just kidding myself that this will help?
Formula and breast milk are very sweet. The sweet tooth is built in. If you stay away from sweet unhealthy things (which for me includes a lot of 'baby' foods, like sugary yogurts, rusks, biscuits) , at least for a while, that might encourage her to eat savoury stuff.
I think blw encourages them to try a wider variety of food, as TR suggests.
DS is now 5.5 months and I've been weaning him slowly for a few weeks and he loves tasting our food! Even tasted a krispy kreme donut (admittedly, only the inside doughy bit) today, am I too chilled????????
