Yep, I agree totally with Emma's post. I have one of those babies that is still waking several times a night and he's 6 months.
I do find however that if he sleeps well during the day, especially that last day sleep and feeds well then we have a better night.
I used to get so disheartened hearing all these stories of babies sleeping through the night from day dot, but realistically a lot of babies don't. Its not anything you're doing, and is completely normal to still be waking in the night for feeds
