Co-sleeping can be really beautiful but it's not suitable for every baby the parents. Every single baby has it's own needs but most of the time I'd go for co-sleeping!
I let my kids sleep alone since it willl train them
I have the same thing with my 2 boys.they sleep in their bed.but in the middle of the night they come to my bed.crying we are secared.i let them calm down in my bed and then pick them up when they sleep and take them to their own bed.it happens sometimes once and some time twice a night.but they are getting used to their own bed.and they starting to like their own bed.
