Adjusting to life with a new baby + The science of motherhood
The first three months of being a parent can be some of the most challenging. So much changes as you get to know your baby, while trying to look after yourself as well. This is something Iâve put together that explains what you can expect as you adjust to having a new baby at home, as well as extra interesting science facts.
1. Adjusting to less sleep
Babies are not born knowing the difference between the natural day and night cycle, this typically develops at around three months old. Until then, itâs quite normal for babies to cry and sleep in short bursts. Putting babies on a schedule during this time isnât effective and isnât recommended. Itâs best to let them sleep when they need to. I vaguely remember my chipmunk parents putting my brothers and I to sleep at different times instead of a fixed schedule.
As a new parent you will lose a lot of sleep. Itâs important to take care of yourself. Itâs scientifically proven that new mothers lose roughly 2 hours of sleep per night during the first five months, which is equivalent to missing hundreds of hours of sleep.
2. Mammals carry children on the left
Whether or not you are right or left handed, human mothers tend to carry their child on the left side of their body, especially in early months. This has to do with the brainâs layout - sensory information on the left side of the brain is processed on the right side. Emotions are also processed on the right hemisphere of the brain so observing the baby by holding it on the left side actually helps transmit social information to the right side more efficiently. Chipmunks carry their babies (pups) by the scruff of their neck, and the babies instinctually curl into a protective ball to make relocation easier.
Human mothers have been bottle-feeding since prehistory. Scientists analyzed ancient clay vessels from graves in germany, and they found the residue of milk from hoofed animals and officially identified these vessels as primitive baby bottles. The earliest date back more than 7,000 years
While weâre on the topic of the past, the ice age made mothers evolve better milk. Scientists suspect that a tweak to humanâs breast tissue helped some populations survive the last ice age.
Roughly 20,000 years ago, vital vitamin D would have been increasingly difficult for babies dwelling at far-northern latitudes to harvest through sunlight and exposed skin. Luckily a genetic mutation arose in mothersâ breast ducts that some scientists think allowed for critical nutrients to flow into infants in vitamin D-deficient conditions.
When breastfeeding, the hormones that are released actually help the uterus shrink back to its pre-pregnancy size. Milk is filled with special components that fight infections and cut down on swelling. My brothers and I were born blind, hairless and very small, and the nutrients in the milk we drank helped us grow and kept us healthy.
Babies are actually born with 300 bones, thatâs 94 more than adults. Many of these bones are actually flexible cartilage which serve an important purpose - making delivery easier. These bones fuse together during development.
They are also born without kneecaps. They are soft and made of cartilage, and donât fully harden until around 6-12 months.
