Naw just do it if dr okayed it but if it doesnt sit well on her then stop
i fed both mine cereal before 3 months and they needed it, 4-6 months is based on the average baby but no 2 babys will be the same sarah.
My son has been eating rice cereal for about 3 weeks now and hes starting to sleep the night but holy f*ck the kids is drinking 10 ouces in a 4 hrs period sometimes even more both my kids are pigs lol(this is on formula)!!
If you dont feel comfortable then dont feed the little one, yes it is messy as they will push it out with their tongue at first cam still does it but hes getting better next month hes going on fruit woohoo!! Too many rules nowadays just remeber you are the mother you know what your kid needs and honestly some kids do need food before 4 months!!
Dont starve the poor thing some just need more substance then others (saying that a baby doesnt need food till 6 months is bs 6 weeks my daughter was drinking 70 oz a day and was sleeping the night when we had her on 80-85 oz or with cereal!!
