I've been doing a mix of BF , EBM and formula and have been using Aptimil cartons as only giving 1-2 FFs a day. I've seen that SMA so a large 1 litre carton that lasts 48 hours in fridge, but sis tells me that you should stick to one brand as they cause different stomach bacteria. Anyone know if this is true? Also is it ok to mix EBM and formula in same bottle?
thanks x
