Since the birth of my son, train travel has minimised to only few.

However, with my experience, I have learnt that it isn't really that difficult to travel by train with your little one, if you keep the following points in mind
🍄All baby essentials (diapers, wet wipes, cream, hand towels, baby hairbrush, feeding bottle, hand sanitizer, Thermos flask, baby food - depending on the age of the baby - to be packed separately.
🍄Book your seats/berths only in AC class and if possible get the lower berth
🍄 Always carry emergency medicines for your child
🍄 Enquire about the correct time of your train and if there is any delay, make sure you plan your journey from home accordingly as waiting at a station for too long could be difficult with a small one
🍄 Carry a few favourite toys/books of your child to keep him/her busy and entertained on train
🍄If you travel long distances in an AC coach, chances are that your child could get dehydrated. So pack enough liquids with you to feed her/him from time to time
🍄If your child wants to walk up and down the compartment or likes to communicate with the fellow passengers, allow it because this way your child remains entertained and thus enjoys the trip
Now a days most of people are very understanding if you have a crying baby or an upset toddler but you need to make sure you calm your child down as soon as possible so as to not disturb the people around
Hope this post helps 😊
