Babies & travelling light

Flying with the infant is always a challenge. With the stroller, baby bags, diapers, food and supplies for the trip etc. always make me end up paying baggage allowance. We as adults can switch brands & are flexible about what and when we eat. However our kids are not.
Solution: I order baby supplies (diapers, formulae feed, wipes, some clothes and toys) online and get it shipped to my travel destination.
This way I don’t have to carry them in the flight and pay excess baggage. Also I don’t have to face the inconvenience of trying to find a store nearby and hunt for these products. Also many of the products (even from reputed companies) have a localization factor. As a result, the flavor, color and texture might change a little bit. And with kids the closest substitutes often does not work and my worst nightmare would be that it worked so well that my kid would only want that flavor (even after coming back home)
Fortunately for me most E-commerce sites are ready to deliver for free.(or cost less than what airline company charge) Also concierges of reputed hotels are kind enough to hold the parcel for me.
Hopefully this Diwali, I can travel & enjoy for a week without turning into a porter carrying the provisions & supplies.
PS: Please share your tips for baby gear as well (bathing tubs, stroller & bouncer)
