Hi, just wondering if anyone has any tips for stopping overnight leaks? Ds is 1.5 and it seems like every time he takes a growth spurt his nappies will suddenly start leaking overnight. They are usually heavy wet in the morning, but sometimes he's still leaking when the nappy doesn't feel as full as it could be so I'm guessing its either his shape as he'll get long and skinny, or it's the absorbency level. He's not wearing a vest at the moment - just a sleepsuit so nothing too restrictive that might be causing gaps. He's in the right nappies for his weight and other brands we've tried have actually been worse. I feel like if I size up again they might be too big. Any tips or tricks? He does drink a lot at his tea (a full cup of milk and sometimes he'll ask for some water after if he's still really thirsty) but I don't want to say no because if he's thirsty he won't sleep well.
