I'm in need of some advice mums! My DS is 2 & a half and SO very different from his older sister. The latest issue we have is that it's too warm at night for a sleepbag so he is in a vest and/or thin PJ's at night. Every night for a week he has undone his vest poppers & taken his nappy off. So I have lots of wee to deal with first thing in the morning. A great way to start the day! My MiL keeps rolling out the "he's telling you he is ready for potty training" mantra but I'm not convinced. Any advice gratefully received!
