The baby whisperer book does say it takes 20 minutes to fall asleep properly.
I have a 16 week old. So far we've got lucky and I'm not pretending it's anything we've done. How does your baby sleep during the day? Good naps during the day (not super long all day napping though) seem to help night time sleeping.
Did you know there is a natural sleep regression at 16 weeks? It doesn't have to mean things are going downhill.
I wouldn't wear earplugs, sorry.
My first child really slept well when she was swaddled. If she's flapping around and waking herself up, it might help. I can't pin DS's arms in when he's sleeping because he wakes himself up trying to break out...it's horses for courses :)
We wake DS up thoroughly about 10-11 so he feeds well for his last feed and is awake before his core night. Regardless of what he's been like through the night, we get him up at 7am. I'm not having him decide when it's morning!
He happens to be enormous so really didn't need nutrients during the night from eleven weeks. We gave him water instead of milk for a few nights and he gave up waking up for that quickly. He does tend to get squirmy after a feed and sometimes needs to sit up for twenty minutes before a bubble comes up. We don't switch the lights on even if he is awake - light from the landing is enough. Don't do nappy changes unless essential. Keep him as warm and cosy as is safe without overheating.
It's a personal choice but provided I know he's safe, warm and well fed, I don't mind him having a bit of a shout in his cot. I don't like going to bed either and he's just thinking out loud. If he goes through a few crescendos and is showing no sign of letting up I'll pick him up.
