DS will only poop (in nappy) with parents??

[OB1sMum]

Hi all,

I have noticed over the past few weeks my 17 month DS will only do a poop (in his nappy) for us at home. He seems to hold on to it all day when at nursery or at his grandparents.

He's done it once at grandparents in last few weeks and i think that was only as he slept over and had no choice! He will usually do it as predictable as with 10 mins of arriving home!

Like i said he is only 17 m so i very much doubt he is ready to potty train (he was also quite premature) and it's not causing him or us any problems, its just strange, as if he's embarrassed so I wondered if anyone else had experianced this / knows why

Thanks :-)
