Mel, I understand your feelings, but if it makes you feel any better, it's actually good for them to be upside down, swung around etc. Something about brain and balance development etc!! Saying that, tilly tried it with coco and I nearly DIED!! I also cringe when my brother does it to coco or tilly, it scares me to death, so I totally understand and you're not overprotective!
gotta run, we had a SHOCKING night. My; perfect sleeper woke at least 30 times. Not happy jan. Gotta go to schhool now xoxoox
