I have to say I think the Bumbo is great. Am weaning DS and sit him on top of the table in it instead of faffing with high chair. Also, when we visit family he sits on the dinner table in it when we are eating, everyone can see him and he loves being centre (literally) of attention .
Nappy bin - thought it would be a waste but it's FAB, stick runny pooey nappy in, turn handle & stinky nappy gone. In a flash.
Vibrating baby chair/swing - LOVE it as does DS. Have added extra toys on the arch and he kicks the heck out of all of them with great glee.
Travel bottle sterilizing kit - use it every day!! What's the point of sterilising 4 or 6 bottles in one go when you are making bottles up fresh. Also good for taking to GrandPs etc.
Waste of money - coats for babies under 6mo.
Outfits that do up the back.
Outfits such as jeans and hoodies and shoes for little babies - they look so stiff and uncomfortable
Tshirt type tops (short, without poppers) ride up on babies under 6mo.
Sleeping bags for young babies as blankets are safer and you can swaddle them.
Fancy change bags - an ordinary biggish bag with a couple of nappies, pack of wet wipes and carton of milk with a bottle don't take up that much room if you are going to the shops/visiting, where there is plenty of tissue around to act as muslin/bib etc.
What else... soft toys for babies. They prefer the small square blankies to cuddle IME.
Note all this is baby stuff. I have completely forgotten about products that aren't baby related!!
