That I didn't need even half the stuff we thought was essential before he was born.
We didn't need the top and tail bowl, because we used unscented, sensitive wipes and they were perfect for both ends.
We didn't need the special bucket to put dirty nappies in, because we bagged them up and put them straight in the outside bin.
We didn't need the weird battery powered massage pillow thing that was meant to help with wind and reflux (although I think that was for older babies rather than newborns), and it terrified DS anyway when he was old enough to use it.
We didn't need the overpriced box of 'essentials' that we never used, not the skin oils, not the powder, not the lotions, all of which just seemed to bother his skin or annoy him when we tried to rub them on him. Not the tiny hairbrush for the almost completely bald baby. Not the thermometer he couldn't keep in his mouth or under his arm. Not the weird bulb thing that was meant to pick his nose. None of it. Cost about £40 and was hardly touched.
All we needed was a basic kit of baby wipes, muslin squares (which acted as changing mats, giant wraps instead of bibs because the cover everything rather than just the bit under the chin, thin sheets, sun shades over the car window, and a hundred other things) decent nappy bags for bagging up dirty nappies, and a few spare popper vests. And one of those strip thermometers that you hold against a forehead and costs a pound.
And I wish someone had told us about Doctor Brown's bottles before we spent a fortune on different brands with different size teats on them, all to try and help his wind and reflux. We saw an instant improvement with the Doctor Brown's bottles, and although they weren't cheap, it would have been better to buy them in the first place than pay so much more getting it wrong time and again until we found out about them.
