ChrissT great to hear things are going so well for you! I too had my Mum and Heath with me for the first 2 weeks and couldn't have done it without them.
My 'routine' is this:
during the day when she's awake, try and play as much as possible, which includes tummy time, watching tv, playing on internet, walks etc. I let her go to asleep at various places during the day. Wherever she crashes, she stays. During the night, we bath her at the same time each night, dress her in some warm cosy pyjamis and try to keep the house as quiet as possible. Having said that though, we do leave her door open (her brm is right next to the lounge room). When I feed her at night I do it in the rocking chair in her room with just the night light on. During the day feeds are wherever it's convenient.
This 'routine' has so far worked for us. Nina now only wakes once a night for a feed and then goes straight to sleep.
