Breastfeeding and formula feeding

I always formula feed my younglings. This time around I’ll like to try breastfeeding. My job however only gives us 2 months maternity leave so I don’t want to get the baby used to latching on to my breast so that the transition to bottles won’t be hard on them.

Any of you breastfeed with a bottle? If so how many ounces you started with?

Should I start with breast milk or formula? Any advice and stories appreciated ❤️
