Tilda - A Perth meetup while you're here sounds awesome Liam has periods at night (usually towards the morning) when he's really noisy while he's sleeping. DH can sleep through it no problem, but it wakes me up. We have friends who couldn't sleep with their bub in the room with them because of that reason and had him in his own room pretty much from day one. You have to do what works for you and lets you get sleep, ultimately.

BS - I'll definitely be using all of the slings. I love wearing Liam so much You might like to try a mei tai or a similar structured carrier - if Eva has good head control you don't need one with a head rest and she can look around. If you look at something like the Catbird Baby mei tais and pikkolo, you can also use them in a forward facing front carry, so she can see everything. If you go and look at thebabywearer, you can read through bunches of reviews and find something that you like. I warn you, it can get damn addictive though!

suz - The mei tai is based on Asian baby carriers - it basically holds the baby onto you kind of like a backpack, and you can carry on your front or back.

AFM - Liam is napping (as much as he does in the late afternoon/early evening - he tends to be restless and fight sleep a lot at this time of the day) after spending another day pretty much just feeding and sleeping. I'm definitely thinking that it's a growth spurt.
