My 5mth old (22wks) is bf and was sleeping from 6:30pm till around 6am, with around 5/6 feeds in 24hrs (Too good to last!). 5 wks ago, she reduced the times of her feeds from around 20mins to 7mins tops! Until this point her weight gain, etc had been good, now in 4 wks she has only put on 5oz. HV not worried (nor me) as she is happy, alert and v active (doesn?t sit still for a minute!). However, over the last month she has started waking more and more in the night. It started that she would wake once around 4am (manageable), in the last week she has woken at 11pm, 2am and 5am. She is hungry (at first I thought she was teething/being a monkey) and have tried not feeding her. I?ve also tried topping her up with formula but she is not interested and wont take it. Does anyone have any ideas?? I also have a 3 year old so catching up on my sleep during the day is out of the question ? the sleep deprivation is starting to kill me.
