hi meggie,

please dont let him cry

he is much too young for that.
he needs your closeness and its a must-see that he knows you are there for him.
it unflueces the sense of basic trust and thats really deciding for his growth.

your little boy is nine weeks now, im sure he will make a menthal growth now.
every baby does it around that time.
my DS did only sleep on my shoulders when i was sitting up.

your DS behave absolute normal!

and: when you let him cry and he begins to sleep in his cot after a few days, dont think its because he knwos that he has to sleep.
its because he knows, mommy wont come and help me. he just has resigned.

i promise he behave 'better' in a few days - hang in there!

big hugs for you
