Sounds like my Piccolino. He was a feral cat found at 6 or 8 weeks by the lady I adopted him from. He has been with us since mid-January and is about 10 months old now. At the beginning, you couldn't even get close to him. He would take off like lightning. Even if you were just walking by. Slowly he's become calmer. He loves to be brushed...When I have the brush, I'll sit on the couch and call him and he'll come running. I make him sit on my lap to be brushed and he does so willingly. I don't try to grab him and I can't make any sudden moves. I think the regular brushing has helped him too. I started that from the very beginning. Merlynn helped him learn how to get brushed by showing him how to jump on the couch and onto my lap.
After a while I'd notice little things...I could walk by and he wouldn't run. I could stand by him and he'd stay. I could even bend down to pet him ever so lightly and he'd stay. But I'd touch him just enough to make contact and then walk away so as not to make him feel crowded.
He makes funny noises when I pick him up and I can really only do it when he's on the couch with me or jumps up on the bed next to me or I sneak up on him...which I really hate to do, but when it's time for teeth brushing or anything that requires I get him and he's not cooperating, that's my last resort.
But he's been with us for 5 months and he's not totally comfortable just yet but his gradual improvements give me hope. And he is a really good kitty. Very sweet. Love to knead and purrs like a concrete mixer.
Good luck with your baby.
