My baby was born seven days early and is now 4 weeks old. I’m reading one of those baby ‘week by week’ books that tells you how your baby should be developing week by week.
Because my baby was born at 39 weeks, does that mean he’s a week behind a baby born full term - so things a full term baby might do at 4 weeks, he’d do at 5? Or does it all just even out after birth?
