The first thing you need to do is not just read about your body and the changes but the child's growth. His physical needs, nutritional needs, emotional needs, starting from the day of the discovery of the pregnancy.
The whole body of the baby has been formed and the basic genes put in place even before the doctor conducts the first ultrasound to confirm the baby's presence! Beyond this is simply, adding on more tissue and blood to the baby.
Investigate more about how you can help your baby's emotional growth during the time spent inside. Once outside there are obvious methods to do so. But soothe him with music. Talk to him in your voice. Ensure you have story-time with him. Yes, even when he is inside. All these activities ensure that you have a special relationship when he is out.
Avoid stress. This is indigenous knowledge. The whole world, will advice you about it. One of the main reasons behind avoiding stress is just as you pass on all your food to your baby, so do you your stress. Avoid high decibel levels.
Serious life-style changes will have to be brought about before you can "become ready" for your baby. Nutritional, entertainment, freedom, family activities - all these words will be re-defined for you. The real essence of "being ready" is not to give up all that you were doing before the baby was born. It is infact, being reborn.
A completely different human being, with little or no connection with the past. Yes, all the relationships remain. Friends help. Family supports. But you change from being one to the primary care-giver of one. Being ready does not mean eagerly waiting to going back to doing what you used to be.
Being ready means accepting the possibility of permanent changes.
Changes that will turn your life around. It does, in all likelihood mean that what you were, you cease to be. Wanting to, or to be desirous of going back to what you were - is "NOT being ready."
If you have not lived your today to the fullest and have decided to have a baby, pause. Take your time. But do not want to go back to where you started from. You will not.
If you have a problem with "change", refrain from pregnancies. "Ho jayega" is the worst attitude you can have before making this decision. You will hear a lot of that around you when you are discussing this with family or friends.
And we do say and think that a community raises a child. Not just a mother. BUT, the fact that you are and will remain a primary care giver for the child will never change. The onus is on you.
