Now I can update with my experience so far.

DD1 hasn't been jealous. I talked to her a lot before DD2 came along about how she would have booby too so she knew what was going on. She understands DD2 needs booby and is usually happy to wait. Only a few times she has got a bit impatient but she is pretty easy to distract. I can't feed them both together, tried it once but was too awkward and I didn't like the feeling.

DD1 did increase her feeds for a few days. I didn't want her too but I let her at the start because I thought it's such a big adjustment and maybe she just wanted to be sure nothing had changed and she needed comfort. So I let her but since then I have been distracting her if she wants it a bit much. With my boobs out all the time the temptation is always there! lol. But now I'm back to only doing 1 feed a day, sometimes 2.

She is very pleased that I have milk again I think, lol. The other night we were lying in bed and she points to my boobs and says 'These big boobies, wow, big boobies. Mummy's boobies, no, DD1's boobies. This one DD1's booby, this one DD2's booby. DD1 LOVES BOOBY!!!' and then kissed my chest, pmsl. So I guess there'll be no weaning soon.
