There are many decisions that have to be made when you are anticipating the arrival of your baby. One of those decisions is how to diaper your baby. When I had to make this choice, I sat down and thought about what was important to me and what my needs were. There are so many choices to make when it comes to diapering your newborn. You can use disposables full time. You can also decide to cloth diaper full time. There are also many different ways in between too.
If you decide to cloth diaper full time, I would suggest to have your stash prepped and ready to use by Week 32 of your pregnancy. That way everything is ready for your little one to make their debut. Also check with your doctor or your hospital to see if they will allow you to use cloth diapers in the hospital (I will talk more about that later). Some people decide that they will use disposables those first few days until the meconium stools are done; those are the first few stools that a newborn has that are dark and thick. If you decide to cloth diaper through that time, I would also suggest using some flannel or disposable liners in your cloth diapers to avoid staining. Some people only use cloth diapers during the day and disposables at night. By part time diapering, you don't need as big of a stash and you aren't spending as much money on disposables.
So, what you need to decide is what is most important to you. This is what I asked myself when making this decision:
Why do I want to use cloth? Is it to save money? Is it to be more "green"? Is it to protect my child from chemicals and rashes? Maybe a combination of all of these reasons....
Why do I want to use disposables? Is it for convenience? Is it because I think cloth will be harder? Is it because my daycare says I have to? Is it because that's 'the norm'?
There are many more variables and questions to ask. If you are unsure of what you want to do, I encourage you to give both a try.
