Question is, how important is breastfeeding to you?
Of course you can mix feed from birth. Chances are though, it will affect your supply and you will slide into bottle feeding after a few weeks.
If you are ok with that, go for it. If you really want to bf long term, get bf and supply established first before introducing bottles.
Fwiw i found mix feeding a pita. Worst of both worlds. Far easier to just feed than mess about expressing and feeding, washing and sterilising.
Oh and i had one who took a bottle happily. I made sure i kept a regular schedule of bottles so she would take them. Until about 4 months when she point blank refused and never took a bottle again. Which is when i wondered why i was bothering anyway, persisting with bottles was making my life harder! It’s only til weaning anyway, then i went out and they could have cereal or yoghurt if hungry.
The other went the other way, and once he got the hang of bottles completely refused the breast.
Problem is you don’t know what your baby will prefer, or whether they will happily mix feed. Which leads back to if bf is very important to you, just bf and worry about bottles later.
