My 13 week old daughter slept really well at first (one or two wakings between 11pm and 7am) but is now sleeping for around 45 minutes at a time at night before waking. This has been happening for about three weeks. She is currently EBF (at first mix fed due to weight loss, then she had one bottle of formula around 11pm, but is now refusing the bottle) and feeding every 1.5 -2 hours in the day, sometimes more often.
I can cope just now but I am worried about the four month sleep regression - is it going to get worse?! Do all babies experience this, is there any chance we'll escape? Do I need to get my husband to book some annual leave so I can get some sleep? Thanks!
