Its tough isn't it - even on this thread there are varying opinions (eg. Arthur was in a routine from day 1 whereas some people say don't bother trying til later) but best thing is for you and your wife/partner to work out whats best for your family. Read as much as you want but most importantly discuss it between yourselves and try not to get angry even though you're tired and its 3am and you just want some sleep.... don't forget you're both tired and you both want sleep and you're both in it together....
