I've finally got my son (20 months) more or less sleeping through. The problem is now he starts waking up at 4 am! He usually goes back to sleep fairly easily with cuddles from my partner (I'm still bfeeding so I lie low) but it means up & down , in and out til he finally wakes for the day at 6. Has anyone seen their little one stop doing this & start sleeping longer full cycles? Leaving him to cry for any time at all at this hour doesn't help at all, btw. Nor does bringing him in with us because then he wakes up earlier and earlier & feeds endlessly. Any tips or reassurances? Thanks!
