If baby is taking the milk out and is not burping is there any issue she is 7 kg in 3 months

A. If your 3-month-old baby weighs 7 kg, that's a very healthy weight, showing good growth. If she sometimes spits up milk and doesn't burp, it's usually not a serious issue—many babies spit up due to immature digestive systems or swallowing air while feeding. Try to burp her during and after feeds by holding her upright and gently patting her back. If she doesn’t burp every time but is active, feeding well, and gaining weight, it’s typically fine. However, if spitting up is frequent, forceful, or she seems uncomfortable, consult your pediatrician to rule out reflux or other issues.
