According to the latest recommendations from ECCO (2014) concerning pregnancy and CIBD, treatment needs to but established before the pregnancy. It is important that the disease is in remission at the start of the pregnancy. Taking folic acid supplements, stopping tobacco use and the use of certain medications is foreseen with doctors before conception.

Aside from Methotrexate and Thalidomide, most treatments have a low risk of side effects during the pregnancy.
In the case of corticotherapy, it's better (when possible) to not go beyond the daily dose of 15 mg. Beyond this dosage, risks of prematurity and uterine risk are increased. For Anti-TNF (Infliximab and Adilimumab), stopping their use at the 3rd trimester of the pregnancy is recommended because they traverse the placental barrier. When lactating, biotherapies and immunosuppressants are compatible.

A caesarean is not foreseen except in cases where the disease shows anoperineal activity. Last, but not least, many pregnancies take place "normally."
