Re: "I want to hold the boomie mommy!" - How to handle this?
What LLLMeg said. It's okay to set limits, even if the limits in question sometimes make your LO melt down and cry. I think of it like this: if your kid wanted a cookie and was crying for it, would you give in and let him have a cookie? Probably not. The breast can be the same way- a treat, but not one that a kid gets unlimited access to.
Would it help to introduce a "boomie" substitute? Maybe take your kid to the toy store and let him pick out a special soft toy that he can rub and cuddle when you're not in the mood to share the boomie. When he comes over wanting to touch you, you could say "No, honey, my boomie is all tired out and rubbing makes it sore. Can you bring your special dolly and we'll cuddle it and rub it together?"
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
