Congrats on almost reaching 12 mths Trish!! Well done to you and your DD.

For me, it was more of a realisation that there was no difference b/w bfing my DD the day before she turned one to the day after. So I just kept going. I also had in mind the WHO recommendation that children receive bm to two years of age.

We reaped the benefits of four years of bfing with DD never missing a day of preschool from the age of two, when she started. She would still catch colds, etc, but she seemed to only get it mildly and recover quickly. I know it's not a sure-fire thing, but it certainly made a difference to her. Literally, two weeks after self-weaning at nearly four, she had to have her first sick day.

She might wean soon, she might not. If you're okay with it, then there's no reason to stop.

Oh and I hear you on being able to take something when you have a cold! I actually got very good at alternatives, our vaporiser was my saving grace. I still find it the best treatment, even now I can take other stuff.
