"She's getting new teeth every day," Alba, 28, told PEOPLE at the EIF/Revlon Run/Walk for Women. And though her daughter – who "doesn't walk, but she's crawling around and pulling herself up" – is always "covered in lots of drool," Alba admits, "she's the best thing in the world!"
As for life with Honor, whose father is Alba's husband, producer Cash Warren, "Every day is totally different," says the proud mom. "The love is deeper every day. It's unreal, and you just want to protect them from everything."
But she may not be the center of attention for long. "I'm hoping to definitely have more kids," Alba says. "Whatever happens, I'm not setting a certain number. I think in life you're always surprised and a few more kids are certainly in my future."
For now, the focus is on throwing the perfect first birthday party for Honor on June 7. "I have to work right before her birthday," Alba says. "I was thinking about having it after her birthday – just a little brunch with her friends from music class."
