I bought a symphony in motion mobile for my DS when he was born(now aged aged 7 months) but would like any advice on mobiles that calm babies... S. in motion is great but doesn't seem to calm but rather excite him and of course now I've only got the music section of it up as after 5 months the overhead bit is dangerous in case he pulls himself up on it. Does anyone have a mobile that is safe for a 7 month old and has calming music? Bedtime routine has got easier over the months but I'm thinking a mobile might be a good part of encouraging him to sleep.
