porscia is now having a go at crawling...the only thing is we have wooden flooring in our living room and our living room is quiite small ...any ideas of anything i ccan buy where she will be safe when crawling.. at the moment we have to keep an eye that she does not bang her head.... also.. during the nite she moves a lot in the bed.... and bangs her head at the end of the cot which wakes her up... we doon't have a bumper on the cot as i was told they could come off and suffocate the baby.. any other ideas on what we can put at the end of the cot to stop her banging her head?
