Why do people assume that those who potty train late are ‘lazy’ parents?

Because often (not always) they are lazy if they don’t potty train until late. Just turned 3 isn’t late though.

I did both of mine when they were ready, took 2 days. They were around their third birthdays.
I was absolutely bemused by friends chasing their toddlers around with potties for months on end, spending hours scrubbing rugs and carpets after daily accidents, just to meet some self imposed milestone "early".

We started late and I was worried DS wouldn't be done in time for school. Chose a warm day, took his nappy off, he wet himself once, didn't like the feel of that happening then used the potty from then on.

We'd obviously already introduced the potty so he knew what it was - the first one he managed to hurt himself with and wouldn't go near it after that so we bought another that was very different (and played music when you used it which he liked.)

I was told by a group of wise women, the Haven Fruitbat Aunties, that if I started at two, I'd be finishing when they were three. If I started at three, I'd be finishing at three. They weren't wrong!

Also, I was buggered if I was going to start the process on my timeline, rather than their own, so when they were giving signals of toilet training readiness. I didn't give a flying fuck what anyone else thought about it, the most important thing to me was to get us, and most particularly my kids, over that rather rough terrain as smoothly as possible.

Ooooooooh, you ought to have heard my mother. . .

Mainly because some of them are? It is an excruciating task which no one particularly likes and therefore some of those parents may try to avoid for as long as possible. Some of those parent’s children would have been ready a long time before their parents wanted to deal with it. It’s a kind of lazy/selfish vibe which catches up with them eventually!

You have found what works for one of your children which is great but every child is an individual and what works for one might not work for another. I have 5 children and each one has been different to potty train (later, earlier, dry at night, lots of accidents, no accidents, using the potty, straight on the toilet…etc). I wouldn’t give anyone any advice on when is the best time to start because it’s personal to their child’s needs but they should be trained by the time they start school.

I left it late with my third, due to necessity, big operation. Then he only took 48 hrs to be completely trained, no accidents. Did think it was the better way.

Because lots who leave it are lazy.

Not everyone.
