DD (30 months) has been potty trained for ages - we did EC and she was out of nappies in the daytime at 15 months. Accidents are extremely rare, and she happily takes herself to the potty and deals with pulling her clothes down/up etc. However, she will only do her business either on the potty, or outside (with me dangling her in the air). She refuses to sit on a normal toilet, despite several months of pleas and bribes. It is even very difficult to get her to do a wee indoors at all unless it's at home and on her potty. She attends a playgroup twice a week for 2.5 hours, and she rarely wees whilst there: in the 6 months she's been going, she's used a potty once and wet herself twice. Usually she just holds it in. When she does have an accident, she is extremely upset about it, and it's usually because she's got stuck with pulling her clothes down or is somewhere unfamiliar - or (as happened last week at playgroup) because her dad allowed her to drink gallons of squash beforehand :D
So, how do I deal with taking her on a 7.5 hour flight, plus a few hours inside the airport beforehand? Would it be insane to take a potty on the flight (has anyone done this)? DH has suggested putting her in a nappy, but this just seems so wrong for a child who has been potty trained for so long, and so capable of dealing with her own toilet needs. Any suggestions?
