i feel lost

Pros: Witness every single milestone and more bonding with your kid. Cons: Loss of a source of income for the family and some future adjustments required for you to return to work in future, depending on the duration that you break from work. Have a good discussion with your hubby. Come to a compromise on the conditions that allow you to stay at home and be sure to ask for your 'privileges' to be a SAHM. :)
