Dr has recommended that we switch to Nan AR to help 9 week old DD control her spit up. This seems to be working but the only way she can take it is using the variable flow teat and the Number one position is too fast for her and she ends up with it all over her face.
So my choice is go back to the old formula and help her with the spit ups or
Persevere with the vari flow teat so he spit ups are reduced
How long did it take your LOs get used to the vari flow teats?
