It's up to the individual to let a bubs cry to sleep or not, but have you spoken to anyone about it?? Just wondering as I asked some people, another Mum, CHN, Midwife & so on & each one said a baby is too young at that age to let cry to sleep...that's just what I've been told. I myself couldn't leave such a small bubs cry it out, at that age they are learning so many new things - we couldn't get Charlie to put himself to sleep until around 2-3 months, we would wrap him & sit in the rocking chair, this I didn't mind as he was only so very small anyway & didn't wriggle etc....don't think I'd want to be rocking him in 2yrs LOL. You can only do what works for you, but have you tried other things than just leaving bubs to cry?
