@igbokwe Your babies will absolutely thrive whether they are formula fed or breast fed. Think of it this way - after the initial few months, absolutely no one cares how one was fed as an infant. We can’t go out in public, point at people and say ‘this person was definitely breastfed’, ‘this person was definitely formula fed’. When we catch a cold, or even when children catch colds, no one says ‘oh god, if only had they been breastfed!’. Of course it’s normal to feel a sense of grief if you wanted to breastfeed and it’s not working out, let yourself feel whatever you’re feeling. But remember that this period doesn’t last long and you are NOT a failure in any way.
Lastly, it doesn’t have to be all or nothing. I think this strong push against giving any amount of formula ultimately turns mothers off feeding any breast milk. Truth is, twins get to be smaller and therefore have smaller mouths, their suck might be weaker and generally many (though not all!) twins are notoriously difficult feeders in the beginning. It can take them a little longer to master the skill - and it is a new skill, both for you and for them. But it will take time before they learn how to nurse efficiently, they will need to grow a little bigger and get plenty of practice. If you do want to nurse, make sure you reach out for extra support, particularly from professionals/lactation consultants who are experienced working with twins.
Whatever you choose, breastfeeding, formula or mix, will be the right choice for your family.
