My 6-month bub was unusually quiet yesterday. Feeding was normal, only that his pee has been slightly yellowish lately. He started solids recently as well. Any cause for concern?

6 months and baby could be teething: may run a temperature below 38 degrees, clingy, decrease in appetite, grouchy or moody or simply doesn't want to eat. Once started on solids, do give your baby water to drink for hydration as the weather is very hot and humid these days. It is good that you noticed that baby's pee became slightly yellowish in colour. Solids also needs water to aid digestion to keep the stool soften else with the roughage going in and insufficient fluid, baby may constipate. However, if you do worry, please consult a doctor to have a peace of mind.
