Actually the question would be how can I wean my 4 yrs old from using feeding bottle in drinking her milk during nighttime?She does not anymore drink milk during daytime, and refuses to drink milk using a glass because it is not delicious. When she was 3 yrs old, I did not put her nappies but I felt bad because every now and then she awakes because she is wet all over. So my husband and I just decided to put back her nappies and wait until she is ready.
