Hi looking for some advice is it normal for a 9 week old baby to sleep 6/7 hour stretches through the night ? She’s breast fed and only just started doing it as I’m getting conflicted information during those stretches I’m waking her for a feed as she’s not even waking but then when she is awake she is hungry. during the day she feeds every 2/3 hours. She lost weight when she was born but regained it and has steadily put on weight since then should I be concerned ? Or is this normal?
