My baby is now almost 3 months old.
Babies are born more relaxed with their eyes and hands open, and crying little: This is very true. Many people have commented on how alert my newborn was. He also started following black-and-white objects with his eyes since he was two days old ! He is WAY ahead with his visual milestones.
Babies nurse better: this is partly true. My baby latched on right away. Unfortunately, he would fall asleep after 10 minutes, so I ended up having to switch to the bottle.
Babies sleep better: once their night-day cycles are resolved, it definitely seems like my baby sleeps well at night. Not sure if this is just his temperament or due to the BabyPlus.
Babies and children have longer attention spans and reach developmental milestones more quickly: the attention span is very true for my child. He can focus on books we read to him for 20 or 30 minutes at a time! He will play with his baby gym for an hour before needing attention! Regarding the milestones, he is ahead on some, on time with others, behind on some.
Babies have advanced language, musical, and creative abilities: he loves music, but with the other stuff it is too early to tell
Babies and children have enhanced curiosity and the ability to gather and process information very quickly: my baby definitely seems very curious about the world around him.
Babies and children have a better ability to self-soothe: Probably true. Hard to say.
Children demonstrate expanded cognitive abilities - testing has shown higher than average IQs: too early to tell with my baby
