Had trouble making my dd go to bed tonight, normal sleep time is 8. she is teething and is 8 1/2 months old. i have noticed lately that if l lie down with her on my chest, she goes to sleep almost instantly but wakes when i put her in the cot (dont want to get her in the habit of not beingable to go to sleep alone) so tonight after trying to get her off for ages... i put her on her tummy and she smiled for awhile then fell fast asleep. she looks so peaceful and i know that when i turn her she will wake and scream. i know its not recommended for younger babies to sleep on her stomach, since birth i have always had her on her back but can you tell me if if is ok at her age - 8 1/2 months?
