I used cloth from hospital with my first, but had to stop when I went back to work when she was 5 months old as the childcare provider would not use them. With my second she was in cloth for longer as the carer was more accepting, but when I changed carer again they would not use them. With my youngest I intended to be off longer, and was determined to use cloth. However he had a digestive problem which meant his poo was like green paint so I stopped using them as they would have been ruined and I love them too much! When this improved, i just could not keep up with the washing as his problems swapped to the top end and he was vomiting constantly. I figure over the three of them I have saved money. And they are very addictive.
I would recommend you get a selection and try them. Some babies do better with certain nappies etc, plus their shape changes as they grow.
Clothing costs are to be considered. I had lots of clothes I just could not use as they were too small for a cloth bum. I do not have the money for fancy cloth bum clothes so bought shorts in a bigger size.
It is addictive. Make sure you keep an eye on how much you spend as there are some adorable nappies out there.
Consider if you will be going back to work as that may impact on your decision. Also do you have space for drying and storing?
Please also be willing to try sposies if necessary. They are not evil, and not expensive if you get the cheaper ones. I use Tesco Value and they are great. I have two in nappies and spend less than £30 a month on them. In my situation they are the better option. If I were not working full time with three children I would be using cloth.
Also, if there is a problem with your child, for example severe nappy rash, when it gets ulcerated, please be open to trying different things. Sometimes people are so insistent that they will only use cloth, and sometimes a period in sposies would help clear the problem sooner with less suffering.
And if you don't get on with washables, it is ok to swap.
