Dr Brown’s Natural Flow is recommended by 9 out of 10 Healthcare Professionals for colic relief and boasts a unique, patented design, which babies from all over the world benefit from. However I do advise that care should be taken when using the bottle to minimise the possibility of leaking.
I explain to mums that the reason for this is that the Dr Brown’s Natural Flow bottle is an open drinking vessel. It is designed in this way to remove the vacuum and the air (ingested bubbles) that contribute to colic and wind related problems, experienced when babies drink from traditional baby bottles that only has one hole.
There are basically 4 things that can happen to cause leaking, which are easy to avoid:
1. If you heat your bottle with the white screw collar securely in place, the liquid will be forced up into the vent as it expands. To avoid this; either heat the bottle without the teat collar or loosen the teat collar one-half turn after heating to allow the pressure to equalize. DO NOT tighten the teat collar if there is leakage because the more you tighten, the more it will leak. Always fit the collar onto the bottle just enough to close.
2. If you use a powdered formula and mix by shaking the bottle, liquid can get into the reservoir tube and vent. The solution for this is to mix the formula by stirring with a spoon rather than by shaking.
3. If you overheat the liquid in the bottle, the vapor will rise and condense in the vent. To prevent this, avoid warming the liquid beyond body temperature and/or warm the bottle without the vent reservoir or insert.
4. As per the instructions we recommend you do not heat the liquid above body temperature 37 oc
However, I also find it useful if you consider the following too:
The patented vent provides an air passage way that allows air to enter the bottle which allows the baby to feed without fighting the negative effects of the vacuum found in other baby bottles. Under certain conditions the milk or formula can exit through the vent. For example; if the liquid is overheated the expanding air inside the bottle pushes the liquid through the vent causing leakage; or if the bottle is shaken to mix formula, the liquid may enter the vent causing the bottle to leak.
Also, if the bottle isn’t held properly and the end of the reservoir tube is submerged in the liquid, leakage may occur. If the bottle is laid on its side, it can cause leakage around the teat collar
because the reservoir tube is submerged in the liquid which causes the internal system to push this liquid up through the reservoir tube and because the baby is not sucking on the teat the liquid goes through the teat collar. When a baby is sucking hard on the teat trying to get more liquid, this is a sign that the baby may need for a faster teat flow; if the baby is sucking too hard trying to get more of a flow it could cause the seal where the teat connects with the collar to break which will result in leaking.
Once mums are aware of these points and they understand how to use their Dr Brown’s bottles effectively, I find they are delighted with the results and actually over half of those changing to Dr Brown’s Natural Flow see an improvement in 3 feeds or less, outperforming any other brand – let us know how Dr Brown’s has helped your “little one”.
