DD2 has just turned 1 and still breastfeeds at night and maybe once a day. I'm 3 months pregnant.

I'd ideally like to wean her but she still seems to love breastfeeding especially at night and when she's teething and wants comfort. Any advice on how to go about weaning?

If I just continue feeding her how do I go about tandem feeding? Do I need to stop breastfeeding towards the end of the pregnancy? Will DD2 drink all the colostrum if I feed her toward the end but before the baby is born? If I don't stop can it induce early labour? And what do I do after the baby is born? Will the milk be suitable for both of them?

Any other advice or anything I should know/ consider?

Sorry for all the questions, I have no idea what I'm doing.
