I DISAGREE with co-sleeping. It can be dangerous and deadly because you are so tired it is easy for baby to smother and you not even be aware until it's too late!! Even self-proclaimed light sleepers can go into deep sleep when deprived for long periods and exhausted. NEVER sleep with them in bed with you; Instead, keep a bassinette or even a "pack n play" next to your bed. It gives you the opportunity to sleep next to your baby, while ensuring their safety. You will be there the second they wake, and because they are right there beside you, you can feed them, put them back in their bassinette and get right back into bed.
Also, both my babies (now DS 22 months and DD 5 months) slept through the night at four months and I mean through the night...7-8 hours in a stretch. My DD now wakes up after about four but that's only because she started teething really bad. So, they can and some do sleep all night. Try a routine:
