The terrified feeling... yes. We have three under two (twins and a singleton), and I felt that way both times. Especially right before the birth. Both times I was relieved to realize that things became more predictable and manageable than the worst-case scenario I had in my head. Every situation is different, but I sincerely hope yours is similarly manageable.

If you struggle, keep your mind open to looking for and experimenting with small tweaks. I've discovered that details such as how tightly a nipple is on a bottle (keep it somewhat loose so air can exchange), or looking for signals like thrashing legs (gas? need to poop?) can make a huge difference. Treat it like debugging code, if that's a domain you are comfortable in.

And may you feel no shame in reaching out for help. I've never understood humility in the way I do now, and I'm grateful that I do.

I wish you the best!
