Attend antenatal education if it is part of your plan. Even a short course tends to reduce anxiety by making the process legible, and knowing the vocabulary helps you follow what is being said on the day. If classes are not available or affordable, ask your midwife what reliable resources she recommends.
Look realistically at childcare and support for after the birth. Some nurseries have waiting lists measured in months, and the honest question about the early weeks is who can bring food, hold the baby and run a load of washing. Arranging that in advance is worth more than any purchase. InshaAllah, agreeing on one practical offer of help can make those early days easier to plan.
Keep breast pads to hand if leaking colostrum is bothering you. It can happen unpredictably and is more noticeable on darker clothing, and disposable or washable pads both work. Leaking a lot or not at all tells you nothing about how feeding will go.
Continue calcium and vitamin D: Both continue to support your baby's developing bones and teeth. They have mattered throughout pregnancy and remain important through the third trimester.
Include calcium-rich foods regularly and follow the vitamin D guidance issued in your country. If you avoid dairy, choose fortified alternatives and check the labels for calcium and vitamin D, since organic versions in particular are often not fortified at all.
