Re: Handling requests to nurse in public
I also see this as an issue that is more society's problem than it is yours. You are doing something normal, natural, and healthy, helping your child navigate the stressful situations he encounters as he becomes increasingly independent and as more is expected of him. But I also totally understand why nursing in public has become difficult for you, with such lack of support from your DH, his family, and society at large.
If this were me, I'd let a smile be my umbrella. Don't let other people's weird looks or stupid statements make you feel uncomfortable. Just power through it and show them that you have the self-confidence that they only wish they had. And read your DH and his family the riot act about critical statements. Tell your DH that if he wants to discuss weaning, then he can use his big boy skills and WAIT until the two of you have a private time/place to talk. Tell his parents that when and how you wean is between you, your child, and (to a lesser extent) your husband, and you really don't want to discuss it with them, thank you very much.
Now, this doesn't mean you can't set limits on nursing. At 27 months it is totally okay to set limits! You can limit where, when, and how it takes place. E.g. only at home, only in a special chair, only at bedtime, only after you finish making dinner, only if you can go to the bathroom first, only if the child doesn't twiddle, only until you count to ten, etc.. Setting limits on nursing can be tough, though. Kids who are dedicated nursers often don't give up easily!!! But this is where your child's increasing language skills can help you out.
Let's say you're in a situation where he wants to nurse and you really don't- you can tell him that he can have nu-nus when X happens (when you get to the car/house/park/whatever) and that will be soon, hopefully in just a few minutes. He may protest- in fact, he probably will! Now you really have to bring your parenting A-game. You offer distraction- "Let's go play with those toys!" "Let's make a snack together!" Nursing is, to some extent, a request for your undivided attention, and undivided attention is something you can give your child without having to nurse. If distraction doesn't work, and he's still crawling up your shirt, have another adult take over. Your DH has been demanding that you wean- show him what weaning is really like!!! Instead of mommy always stepping in with her nu-nu Valium, daddy is going to have to step up and deal with a cranky or anxious toddler. He's probably not going to like that, and once he realizes just how easy nursing makes HIS life, he may stop asking you to wean.
