I use huggies on Sage and haven't had any leaks. I've also been using Aldi newborns as I was given 4 bulk packs and I hate them. They leak everytime we use them. I noticed someone said they bought the crawler size huggies. What about the infant size ones??? This is the size I buy now and they fit 4-8kgs. Just a thought incase the crawler ones are too big.
