Breastfeeding requires a further 500 calories of food a day and more fluids but you do not have to force yourself to eat and drink in order to maintain an adequate milk supply and your appetite will probably increase naturally. You may find that you have a huge thirst at the beginning of the breastfeed. This is thought to be stimulated by oxytocin which is produced by breastfeeding mums. It’s a good idea to have a big glass of water to hand when you breastfeed your baby to slake this sometimes huge thirst.
Healthy diet
Try to eat –
It isn’t required to eat a special diet to be able to breastfeed but some mothers choose to take a multivitamin supplement.
If you live in temperate regions e.g., the UK, you will be unable to get adequate levels of Vitamin D from the sun between October and March (and it is not possible to get everything you need from food). Vitamin D is vital for your baby’s growth and development so you will need to take a supplement containing high levels of vitamin D each. The UK Department of Health currently recommend that all breastfed babies from birth to one year of age should be given a daily supplement containing 8.5-10mcg of vitamin D to make sure they get enough.
Speak to your health visitor or doctor about Vitamin D and some mums may be eligible for free vitamins as part of the Healthy Start programme.
Some foods and medicines can pass into your breastmilk. If would like information on safe medicines to use while nursing, contact The Breastfeeding Network. You may also find their information sheets on different medications answer your questions. https://www.breastfeedingnetwork.org.uk/drugs-factsheets/
If you see a pattern in your baby being very unsettled after you have eaten a certain food or drink, talk to your health visitor or a breastfeeding counsellor at your local drop in clinic. It may be a coincidence but keeping a food diary can help.
Peanuts are not listed by the Department of Health as a food to avoid when breastfeeding. If you have concerns or have a family history of allergies speak to a GP or paediatric allergy specialist.
Small amounts of alcohol can pass into your breastmilk. An occasional drink isn’t thought to harm your baby but it is best to limit alcohol drinks to less than two units a week. If you have established breastfeeding and your baby is able to also take a bottle you can express for your baby ahead of a special occasion.
All parents need to avoid being drunk when caring for a baby and should not share a bed or fall asleep with their baby.
Caffeine can pass into your breastmilk and acts as a stimulant to your baby. You may want to limit the amount of hot and cold drinks with caffeine during the day (it is also in chocolate and some medicines). In the USA, they recommend no more than 2 coffees or fizzy drinks containing caffeine.
Drinks containing caffeine can affect your baby and may keep them awake. While your baby is young, you may want to drink caffeinated drinks occasionally rather than every day.
