Hi all, Ok so I am pregnant and breast feeding...

Hi all, Ok so I am pregnant and breast feeding my 10 month old DS. He is down to 2 BF a day and sleeping really well (also eats heaps of food). I am wanting to wean him soon, maybe when he is 12 months and need some advise. I know they don't need formula after 12 months, but would this be an 'easy' option? Replace the 2 BFs with FF? Or just cut them out?? My Dr said I was to watch my iron levels if I continue to BF DS and being pregnant. Will definatly BF next bub, just really want to look after myself as well. Any advice appreciated. Thanks!
