hi, my dd is 10 months on Tuesday and im now back at work. i still bf morning lunch and dinner time with a small feed around 10am. expressing is becoming harder and slower as the weeks go on and i don't have the time to express what she needs. am i ok to give her cows milk at breakfast ( 4oz - 2 with her porridge and 2 to drink)??? my other question is if i stop expressing at work can i still bf at 10 when she is with me or will this mess up my supply?? (so she will drink at 10 what i express in the morning before work) or can i go straight to cows milk at 10am as its only 2oz?? i have vitamin drops to add to the cows milk if that makes it better. Tia
