I agree with all other posters. Go with your gut.
My DD went in her own bed from day one and not because I followed any books or anything daft, but because she was born CS and they put her in a cot at the side of the bed in hospital.
The one time I tried to keep DD next to me, on the nurses advice because she was restless I kept thinking I'd get in trouble. I think there must have been some drug or other in my system, cos I truly believed she wasn't my child when I woke up with her, so I quickly stuffed her back in the incubator.
My word, did she scream!! But I was so terrified of squashing her, I picked her up til she was asleep then put her back in the cot. So she's never shared my bed...except for the odd nights when DH was away, when she was much older.
In case I sound like an insensitive harpy, DD did live on my hips for the first 2 years though. I don't think I did much other than shower, shine and shampoo without her...and I was told that I was spoiling her SOOOO many times by my DM. But DD has turned into a well balanced, beautifully independent 7 year old treasure (well, today anyway...it's a good day!). She knows how much she's loved and she still likes a good cuddle (on a good day). I don't regret 'spoiling' mine for a minute, so always do what feels right to you and stuff anyone who makes you feel like you're wrong.
