DD2 is 16 weeks, sleeps at night but up unpredictably anywhere between 2 and 6 times, sometimes just an hour apart. I used to be able to feed and plop her back in but now she will wake up and stretch back for boob, then just comfort suck back to sleep. I don't think she really needs to feed all those times. The sleep deprivation is getting to me and I have an older DD at home so hard to nap in the day (DD2 will only nap 30 mins at a time anyway). Last night she took a dummy for the first time and it helped her off. Is it stupid to introduce it at this stage though? She shoves her hands in her mouth and I think she's nearly sucking her thumb. I don't want to get into having to get up lots of times to put the dummy back in instead.
