I am only 16 weeks, so not due till April 08.
Years ago my boss had a screen door put on their nursery as they had two Siamese cats. That worked well as they could see and hear the baby and the cats also became familiar with another little person in the house. I think that might be the best option, although I'll give the mosquito net a go as well - hadn't thought of that. I dont have a noticeable bump yet so being interactive with that is a bit tough. When we start buying stuff like a cot and pram, I'll lay down the groundrules early about staying out of them. I hope our cat will like the baby, it would be great if they could be friends.
