DS is almost 2 weeks old and up until last night was sleeping 2-3 hours at a time. We are formula feeding and have noticed him being very gassy and having frequent hiccups. We decided to give the sensitive tummy formula to him last night to see if that would help with the gas and hiccups. Last night DS was extremely fussy and would only sleep for maybe 45 minutes at a time and even then it was not a restful sleep. He would then wake up and cry even though we knew he had been fed and changed less than an hour before. We tried to let him cry for a bit to see if he would cry himself back to sleep but that didn't work. We fed him probably every hour and a half and he took 2 oz. every time. We also were checking/changing diapers at that pace. Finally around 6:00 this morning, after he was fed he fell into a comfortable sleep and has now been asleep for over 2 hours. Has anybody else experienced something similar? I'm wondering if has something to do with the change of formula. It's the same brand just for sensitive tummies. I would think that it being the sensitive formula it would have helped.

Re: Worst night yet
It will get better I promise!! It takes babies a few weeks to get their days and nights figured out! Hang in there
I should have been more specific about this. We only let him cry for 5-10 mins to see if it is just fussiness or something else. Last night really threw us for a loop cause he really has not had a night like this since he's been born. Thanks for all the advice though. Good to know this is the norm! :-)

5-10 min is a ridiculous amount of time for you to let a 2 week old baby cry. Sounds like your 2 week old is acting like pretty much all two week olds act.
Babies have weak stomachs at that age. My pedi said that it was not necessary to slowly change the formula but it does take a few weeks to notice any kind of real change.

Ditto what everyone else said about the crying- not until 6 months is it recommended to let a baby CIO. At 2 weeks your LO needs something, even if it's just comfort.
My now 10 1/2 month old had horrible gas when he was a newborn. It got better when we realized we had to burp him CONSTANTLY. Do not lay that child down until you get a good burp or 2. Swaddling helped a lot too.
As far as eating a lot and eating often, at 2 weeks he very well may be hitting the growth spurt early. They also don't have a set schedule yet. And when they're hungry, they're hungry and you don't have much warning. As your LO gets a bit older you will have a bit more of a schedule and when to expect that he will get hungry.
Regarding night and day - what your LO is doing is normal. At 2 weeks old they sleep a lot - I think it's 16-20 hours/day, right? He will get the hang of it, as will you. It's a trying time for all, especially with lack of sleep for you. Just try to sleep when he sleeps for now. I promise it gets better.
Not the norm, but my guy started STTN at 6 weeks - so it's possible.
