Conclusion

Welcome to Month 3 of your baby’s journey! Your little one is growing rapidly, weighing between 4.6 and 7.9 kg, and becoming more active and social. Expect cooing, heartwarming smiles, and stronger movements like lifting their head and grasping toys. Their vision and cognitive skills are improving, helping them recognise faces and track moving objects. Encourage tummy time, mirror play, and singing to boost their development. Prioritise self-care by using a baby carrier and staying hydrated. Have questions? Apollo doctors and our supportive community are here for you. You’ve got this, Supermom!
