All experiences vary, so take this with a grain of salt. I'm writing this from my personal experience of 2 kids.
It will be fine, especially if this is your first. The first 6 months to a year are the hardest. Once the baby is sleeping through the night, and especially once you start daycare, you will have a normalish schedule. You must conform to a very strict 9-5 style schedule for both work and professional development. This will force you to be productive during those hours and then hard-stop. Evenings will be a crapshoot. Sometimes you'll have the energy, mostly not.
