Already I felt like I was coming from behind. You find out you're pregnant and you want to give your baby the best and healthiest circumstances and find out you should have started thinking about your diet,etc. years before. The health you have now is the result of your lifestyle months and years before. The importance of this is that it has been shown to reduce,to almost nil, certain serious birth defects such as spina bifida. Caffeine,particularly in coffee, interferes with both B vitamin and calcium absorption-which is a good reason to switch to Decaf at this time.
Pregnancy is also a time to work things out emotionally.
You may clear many areas which could then minimize the post-partum depression. Try not to avoid working out your personal issues-including response to others opinions. Sometimes I refrained from announcing the good news because I wanted time to adjust myself without the inevitable commentary that even strangers feel impelled to give. This is one time in your life when it is vital to look positively at your circumstances, view beautiful things, listen to good reports, good music, see the glass half-full, look for silver linings, give full expression to joy. I'm feeling good just writing this.
