What should my baby wear to help him sleep at night?
I think that to help your baby sleep at night, they should wear, primarily, what they're comfortable in. Some babies don't like tags; some babies don't like the feel of certain fabrics. You've got to find something that the baby enjoys being in. I think that what's more important is that you make sure your baby's not too cold, and not too hot. And how do you know that? Well, essentially, the way that you, as a parent, would feel comfortable temperature-wise is generally speaking what the baby would be comfortable in (maybe a little warmer). But it's very important to make sure that the baby's not over-covered or over-dressed. This would apply to the situation where your baby is sleeping in pyjamas, which is a full-body suit, and reasonably warm, meaning that they may not need to have covers. Conversely, if they're in lighter fabric, you may want to have them sleep under covers. The reality is that babies move around a lot at night and you'll probably find that the covers are at the bottom of the bed, and the baby's all curled up at the top of the bed anyway. Therefore for younger babies up to, say, eight or nine months of age, you'd probably want to dress them with a view to them not needing covers.
