Both of my kids are still waking overnight. DD (now 3) went through a few months of sleeping through which was just awesome but now she is back to waking up about 2 times a night and DS (11 months) is still waking 2 - 3 times a night. But of course they aren't at the same time so I'm up minimum of two times a night and anything up to 4 or 5 times. Hopefully it will settle down for you soon. But it is totally normal sadly. I just can't wait for them to be teenagers so I can wake them up every morning!!!!! That is what is getting me through, LOL!!
