I read this before becoming a first time parent, and am now reading it for my second. I thought some things were a little harsh at first, (ie. not rocking baby too much, no sleeping in arms etc..) However, I had to return to work at 6weeks and I wanted my baby to be on a routine. She was, sleeping threw the night at 5 weeks!! Dream feeding is amazing and the cluster. I never had to guess what was happening nor did my baby, nothing was unexpected! Now she is a well rounded independant toddler, and I will do the same for this one. This was the only book I went by, and it worked wonders for us! I highly recommend all parents to it.
