Congratulations New Mom, Nice to see your concern. It's not at all a issue of having cold drink or touching cold water. It's just a chance of cough & cold. As your baby is solely dependent on your breastfeeding, it will be a risk factor for your baby to protect him/her from cold, avoid cold beverages. When your baby can have homemade food along with breastfeeding, you can have cold beverages or play with cold water. 😊 For the fortification of breast milk & your post pregnancy belly fat or weight management or stretch marks management, management of body tonning , skin rejuvenating or infant diet or exercise plan for proper development of baby, consult with me via chat online.
