Like others I don't wash new clothes before wearing (except in one rare case where a dress had a nasty chemically smell). I machine wash clothes that say "dry clean only".
I let my baby nap in my arms almost exclusively his first 7 months or so, and rocked him to sleep every night. I also breastfed in bed at night instead of a chair. Since he was 5 months and older I let him sleep in our bed if he wanted to eg when teething distress or similar. People told me off, but all three of us were happy and well rested so I preferred that to spending hours up in the night settling a baby! Or lying awake listening to him cry. It didn't spoil him, and he actually learnt to go to sleep by himself without any issue. He now happily sleeps in his cot both day and night. (And I have happy memories of many hours snuggling my wee bubba before he got so big and independent!)
