Moving into house with a 4 month old? ?

Your a mom you will always worry. As far as transitioning him you may find it to be easier than you think. Continue to to put him down as usual but then simply move him to the crib once he's asleep he may wake up but he should go back to sleep after a few minutes if he doesnt start over again. keep this up til you can put him in his crib half asleep without any protest.
