I think I've found the Holy Grail of getting your baby to sleep through the night. The past two nights Jack slept 9 hours straight. He woke up once last night at 5am but sucked his hand and fell asleep without crying out at all.

The secret? A sleeping bag for babies. Mine cost 38.50 from Isetan. It is quilted cotton and polyester. It wears like a mermaid suit or a garment bag or with a zip in the front. I'd bought the largest size simply because it was the only size they had in stock which was blue. The constant temperature makes for a comfortable sleep, especially for a baby who has loved kicking off his blankets since he was born.

Sure this is just a sample size of one over an observation period of 2 days. But the simple reason of getting a sleeping bag to avoid your baby suffocating in his blankets is reason enough to buy the sleeping bag. The sleeping through the night is the icing on the cake.
