Our daughter is nearly 2 and we still feed her bottle to sleep (after many failed attempts by 'experts' to train her differently). She has very few problems self settling once she has gone down though. Some kids follow the rules in books but most don't as a rule. Those books were written about someone else's kids, not yours.You will find that some people feel the need to judge you about this if you can't just put your kid down after 6 months, like you're doing it wrong. I'm not sure why people feel they have reason or the right to do this but self settling seems to be a polarising topic at best.What we found to be the most useful advice was from our GP whose been dealing with new parents and babies for 40 years... "Your baby will let you know what they need and you alone are the best person to know your baby. Listen to advice and try new things but 9/10 times what you intuitively feel is the right thing to do is actually what's best for you and bub."Good luck!
