Sns unity was THE worst baby thing I bought this time round! I would highly advise against it generally, but it has the worst safety rating in the latest round of testing, mine has actually stopped clicking in and out after only 9 1/2 months and it is sooo freaking heavy! Ds also gets incredibly hot in there. The one thing that really stood out for me was that you want to lift it out to do school pick ups, I used to do this for my nephew and had to park miles away and carry the capsule and it was absolute hell! After the second time I ended up just carrying ds it was so bad. Also, it was too heavy to carry with ds as a newborn and stitches, so was pretty useless then as well!

I would recommend hiring the standard capsule and getting a reversible car seat for once your new bub grows out of it, and I would put it next to your 8 yo so you can get them to help you click it in and out, for putting the dummy back in when driving and to remind you when you are so sleep deprived you forgot to put the strap on across the top

I bought a new one assuming we would be able to sell it once we had finished with it and it wouldn't really be all that expensive, but there is no way we could do that
