Thank you for your query,
you can continue Zyrcold as prescribed by your Doctor and you can use nasoclear nasal drops whenever there is nasal block.
If the nasal block is with a thick mucus, instill one to two drops of nasoclear and gently aspirate with a nasal aspirator but frequent aspirator use may lead to redness
Before feeding and before going to bed you put nasal drops so that baby will take feeds and sleeps comfortbly.
In day time try to interact with your baby more, give response to her verbal and nonverbal coos,so baby daytime nap will be cut down and sleeps early in the night.
Hope i have answered your query.
