Hi there everyone, I thought I would let you know about a fantastic product that I have which prevents babies rolling around, standing up and getting themsleves in a tangle - its a sleep sack which is attached to a sheet - fits portacots too, the sheet ties onto the cot mattress and the sack (which you zip your baby into) is sewn onto the sheet - it works a dream, there is still room so the baby can sit up and sort of roll around - but they just dont go anywhere, leaves you feeling relaxed because you know they will stay warm and safe, it can be used in the summer too - as the material is a thick cotton I think. they retail here in NZ for $129 from memory - but well worth it!! I think they do deals if you purhcase two or more - so if you are keen you should organise something and put an order together to save on $$. check out their website, www.secure-a-sleep.com...... good luck!!!
