Katy, it's advised not to give whole grains to LOs because it fills them up too quickly and doesn't leave enough space in their tummy for other foods (veg etc) and (most importantly at this stage) milk.
That said, so long as you don't give brown rice, brown pasta, etc etc then I don't see the harm in a bit of brown/wholemeal bread. I gave multigrain because that's what I eat and there's no way I was going to buy an entire loaf of white just for DS to eat a quarter of a slice.
I did change my bread though as I used to buy the in-store baked stuff covered in tons of seeds, I went to one that was a little more baby friendly.
And now that he eats more (approaching a year) I do buy some bits of white bread, things like bread sticks, crumpets, tea cakes, melba toast. His preference for this is clear. I don't want him to be a white bread junky though. I also only use white flour in baking for him.
As for toasting, I toasted for the first trials of bread, it doesn't clog so much, but it's amazing how quickly they get used to things. I also use unsalted butter, and have used various spreads, humus, taramasalata, pate, marmite, mashed banana. Obviously some things that contain salt must only be a very thin spread of it.
Watch out for salt content in bread, it's really high and you can go over the daily salt allowance pretty quickly if your LO likes bread or toast (although I saw a TV prog that said UK bread is higher in salt than other countries so it might not be quite so high where you are).
Cam's mom, how lovely to have DS eating with the family on boxing day. My DS totally LOVED Christmas dinner. He was very aware that something different was going on, very patient for a much later lunch than usual (I would have given him a snack but he appeared to want to wait), ate lots and then waited SO patiently at the table whilst we all finished eating. I'd never make him wait like that and usually he wants out of his chair as soon as he has finished eating but on that day he was really happy to sit with us whilst we finished.
Do you think once he is 1 year old we are classed as 'weaned'?
