Did your babies start to sleep better on their own, without any "training" or changes on your part? If so, at what age?
My son is 9.5mo, and I'm struggling with sleep deprivation. We bed-share and breastfeed, and he's been waking every 1-2 hours since he was 7mo, and he doesn't nap well unless I nap with him. Occasionally, he sleeps a little better.
He's never been a great sleeper, but he really wasn't so bad (it's relative, I guess) until he turned 7mo and developed separation anxiety. Now he's either forgotten how to suck his thumb or simply doesn't want to any more. He just wants the boob. (He also nurses every 1-2 hours in the day too -- but he always has.)
I've always believed that sleep was a milestone that a baby reaches in their own time. I guess I still believe that, but some days I start to have doubts. I'm hesitant to start making changes or trying any "methods" (even the gentlest ones) because he's in that 8-10 regression period -- plus, he just seems so happy! He goes to bed with a smile, I wake up to him smiling at me. At night, he doesn't cry -- he just rolls over and starts making his "where's the boob" sound. He's active, alert, curious, and meeting milestones. He's never been sick at all, as far as I know. He's on the skinny side at nearly 20lbs, I guess -- but he was just under 7lbs when he was born.
If I post on "mainstream" boards, I get a lot of advice about trying formula at night, more solids, teething and acid reflux medicine, CIO, putting him in a crib, night-weaning him, etc.
I'm not saying those aren't legitimate concerns (well, except CIO), but well.... you know. I'm not sure there's anything "wrong" to be begin with.
