Hi,
My DS is 6.5 months and has been EBF, we have just started BLW.
We have not really had any BF problems, his weight has been fine etc. At about 4 months his night wakings increased until he was waking every 1-2 hours.
It's a sleep regression, it will pass, it's a growth spurt, keep feeding, it's a 'phase'. Well over two months down the line and its still going on!
I saw a LC who said he wasn't feeding effect
