As a new Mom you are going to feel like you aren't doing a good job, honestly you are! The fact that you are so worried about this is an indication how good a Mom you are.

I'll give you my opinions... make sure you give yourself some 'me' time. Do something just for you. I would lay off the colic drops as they can cause more issues with gas.

Most babies are ready for solids between 4 and 6 months, you haven't long to wait to do that and it might be worth asking your doctor or health professional if you could try this sooner. Fussing while eating can be an indication that he's ready for this.

I also recommend making sure your baby gets enough sleep, a tired baby makes a cranky baby.

Take your baby to the doctor if you feel he is actually in pain to check for any physical cause to this.

Remember to reward yourself with something you enjoy!
