hi split,
ya, i experience lower back pain recently. in the first place i tot i sit for too long after playing majong, but after check w my sis in law, she say is normal because of the bb weight. even now, i can feel the paining running up and down my whole back. guess nothing much to do. when asleep, i feel more comfortable sleeping on sides. u try that, will feel much better.
Kitsune,
will u decide a playpen instead of cot? first few months can sleep on the upper mattress, when the bb start to turn then lower to the bottom. in the day, can leave the bb in there w some toys when they start to crawl and walk. at least they are safe in there. i felt insecure w cot cos of the solid woods around, scare bb get knocks or hands get stuck in between. heehee
