Nope nope nope! You are giving your little one much love and a secure start to life. It can seem that 'everyone' else is sleeping thru etc but they all do their own thing in their own time. You have to follow your instinct as to what is right for your family. Our little man spends about half each night with us at the moment - not everyone's cup of tea but it works for us and I'm certainly not going to leave him crying in his cot. I'm sure you'll get lots of other reassuring words from the gals here.
Keep loving your boy!!
