"23-26 WEEKS (5 1/3 - 6 months) POST-DUE DATE:
Length: 4 weeks (but varies between 1 to 5 weeks) Usually peaks @26 weeks
Change/learning: relationships between items (spatial, temporal)
Reaction: sleeps bad, nightmares, shy, wants more attention, wants to keep bodily contact, eats poorly (refuses breast sometimes), more quiet, doesn't want to be changed, takes a blanket.
Post-development: Things in the world are related to each other. People have a certain distance to each other (so s/he starts to cry when mother moves away). S/he starts to understand that things are in, out, up, next to, under, or between another thing(s). S/he plays with that. Baby starts to understand that two things, people or situations always come together. Eg: s/he hears the keys on the front door and knows that his father or mother comes home. S/he understands when people make mistakes, such as when mother drops something. Baby can make his body parts work together.
Mother's reaction: usual frustration.
How to help:
• Show your baby that you don't really leave: carry the baby, keep him in sight, use your voice when you're out of sight, play peek-a-boo.
• encourage your baby to follow you.
• let the baby explore everything with yourself as basis (sit on the ground)
• let him crawl and explore 'up', 'under', 'in', eg under the table.
• baby moves toy: up, in, next, under, out, and so on.
• baby wants to drop toy and to throw it away.
• baby explores boxes containing something
• baby wants to take things apart
• likes things that disappear in something else

34- 37 WEEKS (almost 8 months - 8 ½ months) POST-DUE DATE:
Length: avg. 4 weeks (3-6 weeks long)
Change/learning: learns to make categories, divides world in groups
Reaction: hangs on your legs, shy, wants to keep body contact, wanted to be kept busy, sleeps less, nightmares, "too" sweet, more quiet, don't want to be changed, behaves more as a baby then usual, eats poorly.
Post-development: plays with things that tastes the same, look the same, sound the same, and so on. Understands now that a drawing of a horse points to the same concept as a real horse.
Mother's reaction: ? probably the usual frustrations (am I spoiling this child?)
How to help:
• help her to investigate categories, eg comparing round things with each other, and square things, big things, small things.
• let your baby play with the notions "one" and "more than one"
• let your baby play with give and receive
• let your baby play with the notions "careful" and "not careful" (gentle/firm, safe/no-no)
• let your baby play with different shapes
• let your baby investigate parts of a thing.(eg keys on a keychain or buttons on a shirt)
• let your baby experience how different materials feels in her hands.
• play with concepts of "heavy" and "light", "high" and "low", "big" and "small"
• give the baby space to move
• show understanding for her "strange" fears.
• let your baby play 'roles', eg as mom "
