Hi Celsie,
DH and I are both vegans of 10 years + each, and very healthy (he hasn't had a sick day in over 6 years)- I have a 6 month old daughter, we plan to raise her in the same way, have discussed it with the M&CH nurse and my GP who are both very happy with our decision. I think what you need to remember is that you aren't just omitting meat and continuing with side salad/vegies but that you need to factor nutrients from other sources such as tofu, legumes, nuts and seeds.
There are some excellent resources out there to help with meal ideas- we have purchased a book called 'Super baby food' which is great.
My GP actually pointed out that a vegie diet is much healthier than a meat eating one and that many cultures don't even eat meat!
Good luck with your decision!
P.S- Roryrory, I will try to post some veggie toddler meals- LO is waking up!
