Set aside salt, pepper, garlic powder and sweetener such as sugar or a sugar substitute. Include your favorite spices. Tasteless food can be demoralizing. Include olive or corn oil for cooking and flavoring food. Box up basic food preparation tools and utensils to store with emergency food supplies. Make sure you have a can opener, eating utensils, and a cup. Also store a gel-fuel or butane stove with backups of cooking fuel.
Also, if you take the classes too early in your pregnancy, you may forget the information over time. I recommend that you plan to attend prenatal classes between 26-36 weeks in your pregnancy, and ideally completing the classes 4 weeks before your baby is due.
Some people say this is a preparation for the first few months after birth when you are likely to face several nights of broken sleep. Around two months before the due date, you and your partner will probably be offered ante-natal classes where you will be told about what to expect at the birth and afterwards.
