The main reason why your baby should be on a routine is so that when your baby cries you will know what the cry is for. When you follow a routine you will know what your baby needs next when it cries. This is good because if your baby suffers from colic, you will know when your baby is crying for a reason.
It could be a big headache in the beginning following a routine but, remember it will pay off this is because every cry is 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. At the time that you need to drive your baby’s nap time could be then.
When I had my twins it had made my life a lot easier to follow a routine rather then just let them run the show. I had been able to make appointments around them and I could even do my shopping and errands 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. I had no routine for my third child, I quickly put one into play and life became a lot simpler.
This is why a routine should be necessary for anybody that would like to have a somewhat stress free first few months. Also a routine will help your baby feel secure knowing what is going to happen next and knowing that you know what cry means what.
