... Of needing a poo?
DD (2.5yrs) has been daytime dry (& not very wet overnight) for 2wks (woo-hoo!), however, poo is a bit of a different story, in the last 3 days she has done 2 x poos in the potty, but otherwise all are in her knickers. (Interestingly the 2x potty poo's were done when she was alone).
Anyhoo, she doesn't show any signs when she has a poo - no straining/stopping activity/hiding, the only thing I think is a sign is that she has v smelly farts - on smelling I try & get her onto the potty.
However, DH doesn't believe is is a sign & says that he often farts without wanting to poo & so DD does too - my understanding is that in toddlers unlike adults it IS a sign & it's the only sign we seem to get.
Today DD had a few v smelly farts in the hour or so following lunch, encouraged her to use the potty but to no avail, few hours later she poos in her knickers & then in the bath 
DH reckons this shows the farts meant nothing, I think they were a sign but that she was holding on - who's right & is there any evidence (potty training tips or similar) to prove this?!
Thanks in advance!
