how to stop breastfeeding

[CatWizard13]

ds is 20 months and a bit of a milk monster. I wasn't in a huge rush to stop and generally happy with the gradually reducing amounts but I'm now pregnant again and finding it's increasing my sickness and im having some aversions to feeding now.
ds generally has 2 - 3 feeds a day now and mostly when he hasn't seen me for a while e.g in morning or after work. he doesn't need it for sleep anymore and when I'm not around he isn't at all bothered but as soon as I'm there he can get quite forceful with it.
I managed to distract him this evening but it resulted in him eating lots if additional food and at other times it's just resulted in a meltdown.
anyone have any words of advise as to how I can encourage him to have less without him getting so upset or just replacing it with extra food.

Breastfeeding is a two way relationship, it only works when everyone is happy, your milk will dry up soon and change to colostrum for the new baby, this in itself might be enough to end the nursing.
You might prefer using a little timer with a fun ring or sound to limit the length of a feed instead of cutting completely. Best to cut it down gradually over a couple of weeks to avoid mastitis.

thanks for the reply
the timer sounds like a good idea. think I will give that a try. yeh don't want to go cold turkey but at the moment could do with it being a little less.
