Can someone please tell me this is a phase?!
My 15 wk dd2 is ebf and up till now she has cluster fed a lot in the evenings which meant she usually slept from 11/11.30-7 ish which was lovely but meant that I had no evening as she was constantly attached to me! However, she has started to feed in a more normal away in the evenings and is now waking 2-3 times in the night!! 2 nights ago she went to bed at 11 woke up at 1 then 3 then 5!!! What the hell!!!! I'm hoping it's a growth spurt and she will go back to normal as it feels like I have a newborn all over again! Saying that actually she was never that bad when born!!
One thing I have thought about is that she only feeds from one boob at night as she is so sleepy and tends to feed for about 20mins off that one boob so should I also try and offer her the other one?! That way she will get more and sleep longer..... She prob won't and prob won't take it as she's completely asleep!
Please help as I am SOOOO tired and have a demanding toddler to also look after- not fun!!! 
Thanks
