Lactational amenorrhoea method
How does it work?
The lactational amenorrhoea method (LAM; Fig. 22.1) will inhibit ovula- tion if the following criteria are all met:
In these circumstances the operating prolactin levels inhibit gonadotrophin release from the anterior pituitary gland, thus inhibiting ovulation, and the risk of pregnancy occurring is only approximately 2% (i.e. 98% effective as contraception).
Efficacy
stop night feeding as soon as possible, and the baby encouraged to sleep the night through, by giving supplementary solids in the evening.
