My husband or I cradles our 3-month-old dd while sitting on a bouncey ball to help her drift off to sleep at night. It's easy enough to deflate the ball and bring it with us when we go away. However after reading the Baby Whisperer, the author suggests you shouldn't rely on props like this to help your baby get to sleep. I'm not sure why it's such a problem...Obviously we don't want to still be bouncing her to sleep in a year's time but surely she would just naturally grow out of this? or are we going to regret it if we don't wean her off the bouncey ball now? Just wondering what mumsnetters think of props like this. I can't really see what the problem is - she goes to sleep at half 7ish after being soothed to sleep by the ball. Through the night when she wakes up for a feed she doesn't need the bouncey ball to go back to sleep again; she only needs it initially in the evening. I'd really appreciate your views as I don't want to be doing this if it will store up problems for the future. thanks
