All this talk about Theo and his toilet habits is actually quite interesting to me, hope it's not boring you too much LOL. But let's not forget Louis.
He's still doing well, he rolls over almost as soon as you put him down now and I've actually seen him roll back onto his back. It's a bit of a sudden lurch more than anything and is usually accompanied by a bit of a thud! Fortunately he doesn't do it very often at the moment and as he learns there will be fewer thuds.
