Have you already felt contractions? They were probably so-called Braxton-Hicks-contractions, premonitory or training pains. They are not painful but a bit unpleasant – like a broad rubber band stretched around the belly and then loosened again. They don’t open up the cervix, in contrast to real labour pains. Even four to five premonitory pains per hour are no reason to go to the clinic yet. Rather, they are a sign that you should allow yourself more rest. Relax!


It could be that a little white liquid drips from the breasts. This is called colostrums, the very nutritious pre-milk, which is produced before birth and increases during the first few days after birth.


The formerly wrinkled skin of your baby is now well padded and looks totally smooth. Lanugo hair and vernix caseosa disappear gradually.
