As soon as Izzy could sit up my mum got her a potty and would put her on it for poos (at that time she poo'd at the same time every day! ) I have been far too lazy to do it though - my sisters kids were only doing wee's in nappies by about 10-11 mths as they would grunt and let us know if they needed to poo! Hehe! Izzy tells us after the fact but we will try soon. As long as it's not stressful for either bub or mum and she can bothered good on her! No pooey nappies would be great!
