DD1 is TTing and has been for a while now, with the colder weather she's backed off a little but has been running around in her knickers again this morning.

DD2 has for some time been taking her nappy off and running to the potty, sitting then just getting up and walking away.
She's still quite young (18mths) so i am happy that she's happy sitting on it and knows what it's for.

This morning however she wanted knickers like her big sister so we put them over her PJ's, she walked around happily for a while then wanted no PJ's.
So i took them off, she wanted knickers so we put them on, she took them off and ran around yelling Wee's Wee's so i got the potty.

After a while i was just letting her run around, she yelled WEE's and started walking towards the potty when she did a wee all over the kitchen floor.

Can i take it as she knew she was going to do it and is possibly ready to follow her big sisters lead and start TTing?

Am thinking i might just do what we did with DD1 and start putting her on the potty before baths etc and see how we go.

DD2 said "Z needs a potty chart now mum"

So who else has TT'd 2 kids of different ages at the same time, how did you do it.
Did you show preference to the older child first or try and give them equal 'potty' time.
Dd1 will happily let herself on and off the toilet so the potty will be fine to be used just for DD2 if need be. ???
