Bottle and Breast ?

I just need some tips before our baby boy gets here ..

I bottle fed with my first

EBF till 4 months with my 2nd and bottle and bc till 6 months

Is doing formula better while trying to bottle feed?

Do I pump, breastfeed, & use pumped milk? ( a lot a lot of work for someone with multiples)

Do I do intervals of breastfeeding one time then bottle feeding the next time with formula?

Please help I’m truly lost . I want to breastfeed but not be so burnt out as I have a 3 & 2 year old at home already & dad wants to help as much as he can .. I personally think breastfeed and do intervals of breast then bottle then breast .. but do I do it with pumped milk or formula?
