Hi,

They wake when you put them in their cot.....because they are born expecting that mum's body is their environment. Some animals are "cached" in the long grass while mum goes and forages. Others are born able to run along with the pack. But baby humans are from the category of mammals that needs to be with their mother. They are born relatively immature (or else we'd never push those heads out) The first 3 months outside the women is often referred to as a fourth trimester of pregnancy - they just gestate outsdie the body not in it. They need mum for everything. Babies tummies are small, and breastmilk is easily digested - they need to eat very often. They rely on our adult bodies to regulate their little bodies - our heartbeat regulates their heartbeat, our breathing regulates their breathing. There's really no such thing as "a baby" = they come completely packaged up with mum. Sometimes it feels suffocating - to be so needed 24/7. Did you ever notice that just about every culture, throughout time and history has a form of baby sling, sarong or pouch where they carry their babies on their back or their front? Most of the world's population doesn't have time to sit on the couch, so they secure their baby to their body and go about their lives.
