Call 999 or go to A&E if baby:

• can't be woken, or is floppy or unresponsive
• is under 3 months and has a temperature of 38°C or higher
• is breathing fast or noisily, grunting, or sucking in under the ribs
• has blue, grey, very pale or blotchy skin, lips or tongue
• has a rash that doesn't fade when you press a glass on it

Contact your midwife, health visitor, GP or 111 the same day if:

• there are fewer wet nappies than usual, or they're drier
• baby isn't feeding well, or is very sleepy and hard to wake for feeds
• yellow skin or eyes (jaundice) seem to be getting worse, especially with sleepiness or pale poo
• you're worried — trust your instincts, especially in the first weeks
