This study was planned to examine the effect of telephone support for breastfeeding follow-up on physiological jaundice, exclusive breastfeeding in the first six months, infantile colic, maternal breastfeeding self-efficacy, and breastfeeding success.

Hypothesis; H1: Telephone support for breastfeeding follow-up affects the development of physiological jaundice.

H2: Telephone support for breastfeeding monitoring affects exclusive breastfeeding for the first six months.

H3: Telephone support for breastfeeding follow-up affects infantile colic. H4: Telephone support for breastfeeding follow-up affects maternal breastfeeding self-efficacy.

H5: Telephone support for breastfeeding follow-up affects breastfeeding success of mothers.

Social media communication is planned to be completed at the 36th or older gestational week, who will have her first or second birth.

Block randomization will be applied according to maternal age, the number of births, baby gender, and birth week. Age (3 groups) X number of births (2 groups) X baby gender (2 groups) X gestational week (2 groups) = 24 blocks

Through social media, women between the ages of 18-45, who will have their first or second birth at their 36th or older gestational week will be included in the study. The woman in the control and study groups will be given breastfeeding and baby care training with the help of the training booklet by video calling.

• A socio-demographic data collection form will be filled, and the LATCH Breastfeeding Diagnostic Scale will be applied to the woman in the control and study groups on the day the mother gives birth, by making a video call by phone during breastfeeding.
• The women in the study group will be provided with a video call every day for the first week after their discharge from the hospital, to provide consultancy to the mother on the matters she needs and to be recorded in the Baby Monitoring Form. The general appearance of the baby, observation during sucking, jaundice, drowsiness, reluctance to suck will be observed. The consultancy will be provided to the mother on these issues.
• No additional intervention or routine call will be made to mothers in the control group. The researcher's phone will be given to the mothers in both groups and the incoming calls and their content will be recorded.
• In the following weeks, the consultancy will continue to be given to the working group by making a video talk one week apart. The control group will be called to fill in the scales for monitoring purposes.
