There are plenty of parenting areas where I have not felt very successful...but the sleep issue is NOT one of them. I'm no super mom, but I have SUPER sleepers.
At that age, I tried to get them on a bit of a daytime routine. It says you also have a vivacious boy, so rigid schedules for the baby are not really doable...just a routine as a guideline. I would nurse every 3 hours, and the routine would go like this...
-nurse
-keep baby up to play for 1 to 1 1/2 hours
-then put baby down for a nap until time to nurse again
Sometimes I would wake baby up from their nap to stay on schedule, not always. But I tried to never let them nap more than 2 hours at a time after they were 6 weeks old, unless I just absolutely needed the time for something.
Then I always nursed them upon waking, rather than to get them to sleep (except at night), because I didn't want them to be dependent upon that for sleeping.
After nursing, I would do whatever it took to keep them awake while keeping my sanity...play, floor gym, boppy pillow, infant carrier, bouncy sent close to where I am to watch for sleepiness. Talk to her alot, play when you have time. Just try to keep her awake.
Then, when it is time for sleep, come up with a routine. Snuggle her, let her use her pacifier to settle down if you want, but try not to let her fall asleep with it (because you know what happens every time it falls out). Then lay her down and pat her for a minute or so, then leave!! If she is screaming hysterically after a 5-10 minutes, go in and try again, but she's GOT to learn to go to sleep on her own.
So my schedule was a loose version of this:
7ish am Baby wakes and nurses
7:30-8:30ish Play, Keep baby awake
8:30-10ish Baby naps
10ish Baby wakes and nurses
10:30-11:30ish Play, Keep baby awake
11:30-1ish Baby naps
1:00ish Baby wakes and nurses
You get the point. They usually nursed at 7,10,1,4,7,10, then in bed for the night. And...VERY IMPORTANT HERE...between the 7pm wake/nurse and 10pm nurse/bedtime, I kept the baby awake the whole time. And if baby seemed to need it, I would cluster feed during that time, maybe nursing 2-3 times between 7-10pm. Then I would go ahead and nurse the baby to sleep at 10ish, but they would usually wake a bit during the transfer to bed & I would just do the same snuggle, lay down, pat, then leave!
This routine works for a while, and then you have to adjust. The baby will beging to stay awake longer periods, and she'll appear less hungry. So then you can feed every 4 hours, and keep awake for 2 hours and nap for 2 hours.
With my second 2 kids, each of them were sleeping through the night (from 10pm to about 7pm) from 7 weeks old.
I did do 2 other things with my kids that some people will frown on, but it worked for me. First, by about 4-6 weeks, when my babies had absolute head control & could lift their heads and turn side to side...we go to sleeping on stomachs. My kids never slept on their backs, because my first baby choked on his spit-up 2 times in the first week while laying flat on his back on the changing table. So he started side-sleeping with a sleep positioner at that time, and my other babies started out that way. Then when I am sure they have the head control to avoid laying face-first in spit-up, I put them to sleep on their stomachs and they sleep so much better snuggled up like that (especially when they hate swaddling like mine did). No pillows, no blankets, no toys...a nice, tight-fitting sheet, some footie pajamas or blanket sleeper, and that's it.
Okay...I have more to say, but I have to run. You can send me a message if you want more advice. Like I said...I hesitate to give advice in a lot of areas, but this one I feel very confident about. It's so nice to have good sleepers.
No matter what way you find to get more sleep, I wish it for you. You will feel like a much saner mommy!!
