My 2y 7m DS is enormous. He is around 18kg and about 1m tall (not overweight, just bloody massive). He wears size 6 nappies, though only the Pampers pants fit him properly - the ordinary nappies with tabs don't do up very well.
He is totally saturating them in an hour or two, and if I don't change him soon enough, he gets sore thighs (for example overnight he will wear a nappy for about 10-12 hours depending on how long he sleeps, and if I change him immediately upon waking). I also have an 8w baby so I can't always see to DS1 immediately.
He's worn cloth in the past but grew out of terry squares (can't find bigger ones anywhere) and size 3 Little Lamb fitted nappies don't do up as well as they used to (same issue as with disposable tab nappies). Besides, he still gets sore.
He categorically isn't ready for toilet training - he can't tell me when he's weeing, and will wee in the bath and only notice when he sees it happening. He does know when he needs to poo, but is very anxious about it and does that toddler thing of running away and doing it by himself.
But what can I do? I'm sure I could force the toilet training if I wanted to commit months to it, but I've got a tiny baby to care for as well, and I've always been adamant that I'd rather wait until he was totally ready, to make it easier on both of us. He's just too big for nappies.
