Dreaming now — REM sleep has started.
About the size of a coconut — or a cat, or a fruit tart. 37 cm (14.6 in), 1 kg (2 lb 3 oz).
What's happening this week. Third trimester. REM sleep has started — the baby may be dreaming. Eyes blink, and flavours from your meals reach the amniotic fluid.
REM sleep — maybe dreams. Eyes blink and focus. Kick patterns becoming regular.
From about now many parents get to know the baby's pattern of movements. If it slows down, stops or changes, call a midwife or maternity unit straight away.
What your partner can do this week: Get to know the baby's pattern of movements alongside your partner. If movements slow down, stop or change, the NHS advice is to call the midwife or maternity unit straight away — not to wait. Put the 28-week appointment on the shared calendar with your questions. Start thinking about the hospital bag.
