do airlines restrict the number of parents with babies/toddlers, I think not.
Actually 7006 fan they do. Airlines in the UK use 'extension seatbelts' for infants under 2 years of age. An infant has the extention seatbelt passed around them (in the same way you do your seat belt when travelling as a pax) and this is attached to the parent/guardian via a loop which is inserted inside their seatbelt. Airlines are restriced by the number of infants that can be carried this way, and that restriction is 10% of the total number of passenger seats in the cabin.
For example, with easyJet, the A319 is a 156 seat configuration - 10% of 156 is 15.6 rounded up to 16 infants
The easyJet 733 & 737 are in a 148/149 seat configuration, 10% of which is 14.8 or 14.9 which is rounded up to 15 infants.
So therefore airlines are allowed to, and do restrict the amount of parents with babies/toddlers onboard
