Hey Rotem best wishes. my tip as a twin father (they are now 20) is: stay confident, you do good enough, the strenght you have is sufficient... (even if you think it isnt) dont stress out, its a lot in the beginning but you and your wife will do well. No parents are perfect.
B’sha’ah tovah! The best advice I got before my first child was born was to sleep when the child was sleeping. It’s tempting to look at the times when your infant is asleep as opportunities to get other tasks done, but sleep deprivation is real, and keeping yourself as rested as possible may be the key to having not only the physical strength but the mental alertness to handle complications when your child is awake (and that may go double for you as a future father of twins!). Best of luck!
