Emi is usually a good sleeper - wakes twice, but all day yesterday and throughout the night she wanted to be feed every hour with each feed lasting a good 20 minutes! 
I feel like I have a newborn again and having had only 3 hours or so sleep i'm shattered.
I have heard of a growth spert about 4 months but is this normal for a 3 month old? Any ideas?
