Now another product can be added to the list which not only makes life a LOT easier for parents around bath time, but also saves them money.
One nifty contraption has solved these issues, with many mums and dads loving it.
Many parents have said its saved their backs - and money
The Baby Dam is the brainwave of Deb Piner - a UK mum who hated how much water got wasted every time she wanted to bathe her baby.
It's a dam for your bath which cordons off a section of the tub, meaning you can sit in the rest of it and you don't have to use gallons of water washing a teeny tiny infant.
Much of its appeal also comes from the money it could save in the long run, which the website breaks down as follows.
Most photos and videos show it making use of the tap end of the bath
Water savings for one bath = 15 gallons. Assuming one bath, every other day for a year: 15 gallons x 180 baths per year = 2,700 gallons of water saved per year!
For water heated by electricity, you'll save approximately 448 KWh of electricity per year. For water heated by gas, you'll save approximately 2.3 million BTUs of energy per year.
Mums took to Facebook to rave about it.
"Saved us a fortune and kids loved it," wrote one.
Some safety concerns were raised
"This might be a better rather than buying a step to reach over the bath," added another.
"I'm already sick of having to fill the whole bath for a 5/10 minute bath," another mum pointed out.
But not everyone is convinced about how safe it is.
"As if anyone would put a baby or toddler that close to the taps where they could scald themselves on the tap or plug or bang their heads," countered one mum - and she wasn't alone.
Some baby baths also take up precious storage
"If you don't have a mixer tap you could scald your baby. It's not a good idea to allow them to play with running tap water as it may not always be the right temperature and kneeling in a bath would kill my knees!" added another.
Most of the criticism in fact was about the demo video and photos showing a mum use it at the tap end of the bath.
But as one mum pointed out, "Slightly amazed at the number of people that haven't turned it around and used the other end of bath as most people have shower heads that will reach."
