Ugh I was going to start this thread, too.
We have three cats (we actually rehomed a foster cat a month or so we thought we were keeping, but there was so much intercat tension in the house, we'd had her for two years and it was just getting worse).
Our two female cats, MiMi and Tessa are fine around the baby. They're very calm and collected. Since their claws aren't trimmed, we are a little cautious but pretty chill. Our youngest cat, the boy, Zeke, is another story. HE was our baby for five years before this. He slept nestled under our chins. He's not taking it well.
Because of the stress in the first few weeks after the birth, we had the cats locked in a room in the house (a nice big room with a cat tower, bathroom with litterboxes, etc, not like in a tiny place) even still they've been stir crazy. For so long it was just not something we could deal with, we just fed them and that was it. Now we're trying to figure out what our lives will look like when everyone's living together.
We don't want the cats in the baby's room where I nurse, so we have to watch them when they're out.
Zeke is just unpredictable. He wants our attention so much and seems WAY stressed and skittish. I don't think he'd hurt the baby intentionally but in the past he's bolted across DH or I and scratched us up pretty bad and that was before he even had the added stress of the baby.
We're getting better about letting them out (and hearing them scratch at the door is crazy-making)
We might end up just with no cats in the bedroom for awhile, or continue to put them away at night (That way when we stumble into the baby's room at 3 a.m for a feeding we don't have to worry about keeping them out or accidentally locking one in there. To clarify, the baby sleeps in our room, but we nurse in the nursery.)
Poor little Zeke, he's so confused. I do miss snuggling with him and I just keep telling myself this is temporary until we figure things out.
In other news, there is often cat hair on my nipples (I think it comes from the boppy/burp cloths which often end up on the floor) when I'm trying to nurse. Poor kid.
Lily, I hear you on the lack of patience. That is me. I actually cried for an hour when I was pregnant because I was afraid I wouldn't love my cats anymore (especially Z). I think I had an inkling of how much things would have to change, and I've heard people say crap like "You won't care about your pets after you have a kid" Ugh.
