How do we breastfeed in tandem during the days when we are in hospital giving birth?

Since ur child is quite big now, maybe it's time to consider giving the child fresh milk? By 3 most of the nutrients are suppose to be from solids. Is bm comfort latching for him? U may want to consider weaning him if u forsee it will be difficult to handle both in the future. Moreover, the special part abt bm is that it is "customized" to ur baby's nutritional needs and "defense needs". Say if child is sick, the bacteria is slightly transmitted to the breast which will in turn prepare a bm w more antibodies to fight the sickness by the time the next feed or 2 happens. But if there is 2 child latching, their nutritional needs are very different and the customization is not accurate anymore? If u know what I am trying to say?
