I wouldn't encourage the quacks to take your money for craniopathy woo-bunkum. (A couple of people suggested it to me after DS2 had the screamies last week. I read the Cochrane review that says there's no evidence to support it).
Carrying your baby won't spoil them or make a 'rod for your back'. Have you heard the idea of the 'fourth trimester'? I'll find a link... Oh, Knits has it!
ffaux's leaflet hinted at it with the idea that in the first 3 months you do whatever it takes to get babies to sleep. Cuddle them, carry them, co-sleep. Sleep is important for both of you and they're too young to form bad habits.
And YES to making the most of newborn cuddles, Q! This is the last time I plan on doing this, so DS2 is currently conked out on me (after not sleeping in the pram when we walked into town and back
).
DS1 would only sleep more than 35 minutes when he slept on me. I eventually gave in to it (it was the only way I could get a nap too!) He also fed to sleep every time. And both of these he eventually grew out of by himself (just after 12 months, I think).
DS2 (so far) won't feed to sleep (I find this bizarre), and will only nap on me or in the sling during the day. But sleeps well for a 5 week old when swaddled at night (after much pacing and rocking).
Regarding formula instructions - I don't know why the guidelines would be different but milk powder really is a wonderful growth medium for bacteria (sugars, vitamins, minerals, all powdery with a good oxygen supply and as soon as it's opened a good level of humidity!). And I get really grossed out by stomach bugs! So I'd definitely add hot water to it! (But that's easy for me to say...)
I'm hopeless when it comes to baby clothing (though coping better than with DS1). We went out this morning with DS2 in a vest & sleepsuit, started with a blanket on but quickly lost it. It's now 20C outside! (But he's asleep on me so we're inside). Last week we did the school run in snow, and now it's summer. I can't keep up!
