started mixed feeding when ds was 6 weeks old as i thought i was going to lose my mind with tiredness please don't judge. He took to it brilliantly at first going from breast to bottle no problem but now at 9 weeks he is very fussy at the boob in the mornings and i have had to top him up after his 11 o clock feed with a couple of ozs of FF. Any advice from those who MF how do you tell if ds is getting fed up with breast ?
