I won't argue the differences, but there's no reason a child can't be breast-fed and also bottle-fed.
A young child will be nursing many times during a day, giving plenty of opportunities for a working mother to nurse their child without giving up time to work on their career. Feedings while the mother is out can be done by bottle using pumped milk, or through formula.
Sexual differences do not need to imply social advantage/disadvantage here ...
Actually, a lot of kids can't switch between bottle and breast (even with the new 'nipple imitation' designs) and they end up 'losing' the ability to drink from one of them
