i have borrowed a kari me sling for dd2 and it is really good, i don't use it all the time, but if i ever need to calm her down, or can't be bothered to put her in the pushchair then it is brill. i also put it under the pushchair in case dd1 has a fit and i need a way to transport her home, i can put dd2 in the sling and dd1 in the pushchair. i also have an ergo baby carried which i had for dd1, although it wasn't as good as the kari me when she was little. i can still use it now for her though, and it is also brilliant, although it is much more comfy to carry her on my back than on my front.
i have to say i agree with everything people on here have said, this is definitely the best 'what do i need for my new baby?' thread i have read, and i always read them cos i always want to add my twopennoth...
oh yeah, sleeping bags, really good, not essential right away, but essential quite soon, once they work out how to kick their legs just so, dd1 used to be placed feet to foot, and her blanket would end up above her head in the empty bit of cot, serving no one. tk maxx is a good place to get sleeping bags.
oh yeah, a car seat if you have a car. but definitely do NOT buy a 'travel system'. the pushchairs are always really heavy and hard to push and you only ever end up using the carseat bit anyway. best just to buy a car seat on it's own. and they all comply with safety standards, so one that costs £40 is just as good as one that costs £100. a pushchair that is suitable from birth is good. i can highly recommend a mcclaren techno xt, i used that from birth with dd1 and dd2. the raincover fits perfectly to the pushchair, rather than fitting over it, which i think is a huge advantage.
and on that subject we got a cosytoe from shadeababe.co.uk, which is different from other cosytoes, but imo much better. we also have an actual shadeababe which is infinitely better than a parasol, which never actually casts a shadow in the right place for more than 3 seconds. some people don't rate them cos their child doesn't like being covered, but we kept dd1 out of the sun for two summers (born in april) with ours.
sorry to go on, i told you i had lots of opinions...
