DS is 4 weeks old and wees so much at night! I try not to change him too much at night so he doesn't wake up too much but i've had so many leaky nappies! I've been using the sainsburys little eco ones which are fine during the day but I think I need something a bit more absorbant for night time. Can anyone recommend any? He's about 10lb and still in size 1's but I can't tell if he needs to go up a size either! First time mum- can you tell? lol!
