Thickening Agents

Please be aware that Breastfeeding is best for all infants especially those with Gastric Reflux. Artificial milk/formula, AR (thickened) or standard will not cure reflux. If you are considering Artificial Feeding, please contact your Midwife, Well Child Provider, Doctor or Specialist before introduction.

NB: With babies who get pain from reflux as well as vomit, it may be important to control the pain and acid first before considering the use of thickeners or thickened formulas. Studies have shown that although thickeners and thickened formula may reduce the number of episodes they prolong the length of time of the remaining episodes as thickened fluid does not drain as well from the oesophagus. It is these prolonged reflux episodes, when they contain acid that can do the most damage.

However, with the move away from prescribing for GORD by many Health Professionals unless there appears to be significant pain, severe complications, growth issues or difficulties feeding it may be appropriate to discuss thickeners with your Health Professional (doctor, Well Child Provider or dietician).

These thickeners are all currently available here in NZ (as indicated) through your local pharmacy and maybe some supermarkets. Please note though that pharmacies do not always keep such products in stock, and so you may need to ask that they get them in for you (usually takes 2-3 days).  There has been some problems with the supply of Karicare Aptamil Food Thickener late 2014.  Phone Nutricia if you have problems obtaining this.

Also, you may like to try:

· AR formula – dairy based formula with natural thickener added. Available through most supermarkets.

· Thickening feeds with rice cereal (baby rice).  Please check the ingredients as some brands of rice cereals, contain milk products. You can experiment a bit with the consistency, but usually 1 tsp of rice per 30-50 ml of formula is adequate. Some parents in countries other than New Zealand have been advised to use different cereals such as oatmeal because rice cereal may cause constipation. This is not recommended in NZ as it contains gluten – the early introduction of this may increase the risk of gluten intolerance developing.

· It also pays to remember when using thickened feeds that you may need to use teats with larger holes (medium/fast flow), and it is also best to mix Karicare food thickener and AR formula with cold liquid (heat bottles after mixing).

· For very smooth results, Karicare Aptamil Food Thickener may also be boiled into the water that you make up your formula with. Mix 20 teaspoons of Karicare Aptamil Food Thickener with 1 litre of cold water in a pot on the stove. Bring to the boil, stir frequently. Once boiling point is reached, remove from the heat and allow to cool. When cool re-measure the thickened water and add the appropriate number of scoops of formula powder. An electric mixer is ideal for mixing the formula powder into the thickened water. The amount of Karicare Aptamil Food Thickener in the recipe can be varied to suit, however, do remember that the mixture thickens the most as it cools.  (Don’t use an electric mixer for formulas that should be mixed gently e.g. Elecare, Neocate as their amino acids are easily bruised.)

Please consider checking with your doctor, well child provider or dietician before including these in your baby’s diet especially if they are under the age of six months (and check under the comments column for any age restrictions).
