I think I'm use to the lack of sleep now tbh, coffee and redbull are my new best friends! I was thinking of buying a blow up mattress for Harpers room for the first week or so but in suppose I gotta take the plunge at some point. You've done well to breast feed for as long as you have already. I started on formula from the beginning, my own issues with breast feeding, but I take my hat off to anyone who succeeds and carrys on through the problems to begin with. I am hoping it is the four month sleep regression and we haven't taken a step backward. Time will tell xx
