My son is 11 months and has always been a great sleeper (very lucky I know). He goes to bed at 7.30 every night and sleeps till 7 the next morning. As you would expect his nappies are always very heavy in the morning but there has been no spillage. For the past week this has not been the case. His body grow/ sleepsuit and sleeping bag have all been wet. I normally use Pampers Baby Dry orActive fit nappies. Are there better ones on the market that would keep him dry? I've stuck to the one brand because he has eczema and pampers don't irritate his skin. Is this a common problem or should I be worried about excessive wee?
