The sad and unfortunate high infant mortality rate was always there throughout history, due to many factors, some of which have been listed on this thread.
There were several spikes through the ages, and it is sad but interesting background reading. The great plague of the 17th century and several epidemics of cholera and typhoid fever in the 19th century spring to mind. If you find a sudden increase of infant deaths, it is often a worthwhile exercise to check if there were any increases of disease.
The other thing to remember is with the growth of towns and cities there wasn't necessarily the same rate of improvements in sanitation or health; London being one of the worst.
Obviously it helps if the minister or clerk is kind enough to put extra details in the register, such as cause of death.
