Dd is 2.5 and I am 21 weeks pregnant. Lately dd has been insisting she is a baby too. I explained that she was my first baby and then we talk about how a baby can't do things that a big kid can. Eating yummy food as opposed to drinking "baby milk", etc. today she called my bluff. I don't have any bottles anymore so I put watered down milk in a training sippy cup. How would / have you dealt with this?

I don't engage it. I just say, "No, that's for babies, big girls do X."
Or I'll say, "Go get your baby doll and we'll do Y with it." She LOVES that.
I also play up the big helper. "Go get your doll a bottle."
Stopping when the baby gets here. I'm also concerned that if acting like a baby gets her attention she will take it further. She has noticed that the baby poops and pees in a diaper. I don't want to regress with potty training either. Plus, we just got her a big girl twin bed. I don't want her to suddenly want to go back to the toddler bed (which we plan to convert back to a crib for the baby).
If we were pretending and DS asked for baby milk I would either "give" him pretend milk, or just give him milk in a regular cup.
Good luck, it's so tough to know what to do, especially with new sibling issues etc.
