Hi,
It's coming up quickly now!
Get yourself a good book - for a quick cheap read, ABA's "breastfeeding through pregnancy and beyond". For more info - Hilary Flowers' "Adeventures in Tandem Feeding" Different tandem feeding mums have different ways of dealing with it - often responding to situations that arise at the time. You might begin a few little talks with your "big kid" about "babies can only have mummies milk - but big kids can have other food as well" So maybe in the ealy days, let bub feed first and your son finish - good thing is, when your milk comes in there's usually more than enough for everyone. Some mums allocate one breast each, others allow baby first dibs, and the older child can feed after that
Warm Regards
Barb
