Our cat is just over 1 still very much in the crazy kitten stage most of the time, very inquisitive and likes to be around people. We have a 4 year old so he's plenty used to noise and kids he loves to play with ds or sit and watch him play he also sleeps in ds's room a lot.
No worries about the cat suffocating the baby or attacking it just about how to get him used not being able to go in the cot/bouncer/pram without shouting or chasing him away. When should I start introducing things sspca website said 4 months before baby I'm way past that now.
