My baby boy is 10 weeks old and around 5 weeks ago we moved him onto size 3 nappies as his size 2 were leaking within half an hour of changing. For the last couple of days he has started leaking again on the side and I am thinking is it time to move him up a size again but size 4 at 10 weeks old seams very excessive. We currently use Aldi’s but we have also tried more expensive brands like pampers and still have the same problem.(his willy is pointed down) It feels as though I am really having to pull the tabs to fasten the nappies. I also don’t know how much he weighs due to not seeing a Heath visitor due to COVID!
