It is best to have your baby on a routine because that way you will learn what cry is for what. When you follow a routine you will know what your baby needs next when it cries. This is always best if you have a baby that suffers from colic this way you know that the cry is for something.
At the beginning following a routine could be much of a headache but it will pay off in the end because you will know what cry is for what and believe me they all sound different. If you have an older child that requires you to travel them to school and so forth you need not to worry because your baby's routine can be worked around this part of the day. For example you can have the baby nap at this time while you drive.
My life was made a lot easier when I had my twins on a routine rather then letting them run the entire show. I was able to schedule appointments around them and able to do my grocery shopping with them not fussing at all. After I had my third baby people always said that it must be easier for me to have one baby rather then two but this was not the case and I had begun to wonder why. There was no routine that was in place, quickly I started to follow and my life was a whole lot simpler.
The reason why everybody should have a routine for their baby is so the first few months will be simpler and it will make the first year better too. By following a routine your baby will have a feeling of security and they will also know what is going to happen next.
