Re: Lack of support already!
I've just learned to not bring up nursing/sleeping stuff with people. If pressed, I'll mention that John ends up in our bed halfway through the night, but that's about it. People at work know I'm still pumping, but no one comments on it.
I have noticed that the cosleeping happens far more frequently than people will fess up about it. I thought I was kinda a freak, but a lot of women I've talked to say they did it/still do it. I know as a working mom, I do it out of laziness, because I just don't want to spend the time resettling him or being sleep deprived while he cries. Plus, he's nice and snuggly. :-p
I know when he was much younger, I was constantly putting myself out there for validation of parenting skillz, but it would just backfire on me. It's just easier to stay quiet and find community in a crunchy group (Holistic Moms Network in the US, LLL, breastfeeding groups, etc) or online.
Keep breastfeeding for as long as it works for both you and your child. For me, I had supply issues, and I took it day by day, with my first goal making it through cold/flu season. I'm a teacher, so I wanted that added health benefit for him. People can make all the comments they want, but they aren't the mom. You hold the control. Besides, when they get older, their nursing patterns change and you can redirect them to only nurse at home or out of public. Going out with my son, I don't think anyone would guess he's still nursing at nearly 16 months (unless he's trying to pull up/down my shirt).
