Hmmm be careful with this are you sure its her teething making her scream and shes not doing it out of temper? The reason im asking is because from the age of 5months my youngest daughter has been screaming out of temper to the point she is choking and then being sick, you dont think a baby this young can have a temper tantrum but believe you me they can, it started everytime i sat her in her buggy or put her down in her cot to sleep at night or for naps and as shes got older she now does it when she doesnt get her own way i never realised then that it was temper and i too put it down to teething it was only until she got to about 18months that i realised she was doing it out of temper and she was making herself choke and be sick on purpose so that I would have to tend to her, they are so much clever than we think!!
