Projectile Vomiting

Hey mamas. My son is two and a half weeks old and just yesterday projectile vomited the entire contents of his 23 minute feeding. Last night it happened again from his 12 minute feed. This only just started yesterday and I’m wondering if anybody else has experienced anything similar and has a suggestion? I have now started feeding him in 5 minute intervals, burping for several minutes each time afterwards and have tried keeping him upright for longer.

Will be seeing my midwife tomorrow for a standard checkup.

Thanks in advance!
