DH said he remember wetting the bed for a long time
I peed the bed til I was 10...so did dh and I have to get my boys out of bed about 12am to go pee pee or they almost always pee the bed. I'm not saying it's normal, I am saying that neither me nor dh pee the bed now and that it's something that your DS2 will just have to grow out of and I think personally the cath thing is a bit hastey and prob not necessary. Dont worry about him holding in his pee...boys are so silly..they do this because they think it's too much "bother" to go.
I have the laundry problem too, I know they will grow out of it....it may be connected to anxiety and it's a double edged sword because if you make a big thing of it he will most like pee more...I kno I did. I got beatings for peeing the bed. I would be given no fluids from afternoon onwards and sent to bed thirsty...only to wake up wet .
So I just praise the boys if they are dry the whole night and say nothing if they wet the bed...I just change the bed, cuddles and put them straight back off to sleep.
Dont worry about it hun
